The Military-industrial Scientific Research System of the Academic Master Chapter 997

Chapter 997 Let's have a big fight!

Like Professor Jameson on the stage, most of the people in the audience only experienced a brief moment of confusion after seeing the question, and then quickly realized the essence of the problem.

"It should be a two-phase flow problem of non-Newtonian fluids?"

George asked his two companions in a low voice.

"yes."

Lyles nodded, then showed a playful expression:

"And there are pitfalls hidden in the conditions of this question..."

The other two were stunned when they heard this and looked at the conditions on the big screen again.

It was Hermia who reacted first:

"Gas-liquid two-phase flow?"

According to the process conditions given in the question, approximately two-thirds of the process of substance B will be in the gaseous state rather than the liquid state.

"oh..."

George next to him also smiled knowingly:

"It seems that the tournament wants to use these details to cause us trouble..."

"Although it's an inconspicuous place, I'm afraid many people will be tricked."

Lyles crossed his legs:

"The person who asked this question is very bad..."

In his opinion, this should be a small trick used by the Torch Group against them.

As long as the participating teams from China are given a little reminder, they can be completely avoided.

And if other teams don't pay attention, it will affect their results.

To some extent, it can be regarded as a reasonable use of the host's advantages.

In fact, in numerical calculation software, there is a database for most common fluids.

If the calculation conditions you enter are too outrageous, such as liquid water at 1 bar and 1000°C, there will definitely be a prompt.

But today these two polymer melts are obviously not among the "common" ones.

Although problems will still be discovered in the end, the 48-hour game time is not very generous in the first place. If it is delayed again, it is very likely that the problem will not be completely solved.

If we also consider the mentality affected by this incident, the potential losses will be even greater.

This kind of digging holes in the questions is relatively common in ordinary examinations.

However, competitions, especially high-level competitions, are actually rarely encountered -

Because it is generally not the focus of investigation.

At this time, Hertz, who was next to him, also came over:

"Two-phase flow problems should be the most classic CFD application field. Although COMSOL's advantage in this area is not as great as that of homogeneous turbulence problems, according to our previous tests, the calculation efficiency is also significantly better than that of Torch Group and ANSYS. Taste."

"What happens next depends entirely on you..."

Although nearly 10 teams that have reached an agreement with COMSOL have entered the finals, there is no doubt that these three players from Stanford University, who have been personally coached by Professor Jameson, are their seed teams.

It was also the team that received the most attention before the finals.

After the preliminary round, Hertz's ambitions have expanded a lot.

He has even begun to consider whether it is possible for the three Lyles players to continue their form in the finals and take first place again.

When the time comes to win the first place in the preliminary round and finals, it will be an excellent promotional material.

"Don't worry."

Lyles replied:

"They set up several traps in the questions, but they are not difficult to see."

If he was still a little unsure before seeing the question, now his mentality has basically stabilized.

People are like that sometimes.

If the whole process is completely smooth sailing, you will become suspicious.

But if there are a few small obstacles that don't even play a role, it will feel much better.

However, this part cannot actually be regarded as Chang Haonan's calculation.

In fact, whether the substance is in a gaseous or liquid state has no impact on his plan.

It's just that polymer melts are not very common, and there are even fewer that can be used for injection molding. So when you pick and choose, there are only a few options left that can be used to solve questions.

Others are even more abstract.

As for the unexpected mistake that lowered the opponent's vigilance... it can only be said to be an unintentional move.

After the examination questions were read out, the more than 200 contestants naturally left the conference hall immediately and went to their own examination rooms to start answering questions.

Judging from their expressions, they are basically eager to try.

After all, there is no way that the team that can pass the test and reach the finals is just a random mess.

Everyone can basically see that the difficulty of this question is basically at the boundary of their abilities.

Just a little hop and you'll be there.

And if you can have an epiphany during the process of answering the questions, it may even be possible to further improve your abilities...

The rest of the people in the conference hall started chatting with a relatively relaxed attitude -

Almost everyone, at this point in time, feels that they have taken a big advantage.

Needless to say, scholars and professors, competitions and conferences will have great benefits for the visibility of the entire industry. In the future, whether it is applying for projects or business cooperation, the difficulty will be greatly reduced.

Sponsors, especially those in the chemical industry, were overjoyed after seeing a topic so close to actual production.

This means that numerical computing techniques have at least the potential to reduce their costs in the design and production processes.

As for the three companies that mainly provide numerical calculation services and tools...

COMSOL feels that it has a huge advantage and wins.

ANSYS originally specializes in this type of process production issues, and even provides preset models for a variety of chemical equipment in the software. Although the performance is slightly worse, it is lightweight enough and can be used to win.

Not to mention the Torch Group, Chang Haonan is ready to enjoy the scene when the results come out...

"Dear guests, please stay."

Chang Haonan simply packed up his things, then stood up from his seat and said half-jokingly:

"Don't be anxious, we don't have to take the exam like the contestants..."

One sentence caused a burst of good-natured laughter below.

After briefly livening up the atmosphere, he continued:

"The organizing committee of the conference has arranged a welcome banquet tonight. Please be sure to attend..."

If these people were put back now, they would definitely study the issue simultaneously with the players.

Although Chang Haonan is confident that his hole is very hidden, the people sitting here are also well-known figures in the field of numerical computing.

If you see some clues and find an opportunity to remind the court, it will be troublesome.

Therefore, at least they must be locked in the banquet hall tonight.

As for tomorrow…

It will be too late no matter what you do tomorrow...

At the same time, the participating students had already taken their seats in front of the computers and began to study the question carefully.

The Stanford trio even almost skipped this step—

Lyles' ability is indeed extraordinary. He had almost finished the draft when he was just in the corridor.

Now sitting in front of the computer, after a little review, he started to give instructions directly:

"In the first stage, Hermila was responsible for establishing the physical property models of two substances, A and B, in different states. I handled the geometric model and meshing."

"In the second stage, I dealt with the simulation calculation conditions and the setting of fluid physical parameters and boundary conditions. Hermi was responsible for the modeling of the forming screw and barrel, and at the same time prepared several typical torsion elements...actually the model of the stirring paddle. So that we can test it later.”

"In the third stage, based on the test results of the impeller models with different characteristics, select the best one and optimize it based on it..."

Under his command, Hermia quickly clarified her thoughts and began to handle the first task in an orderly manner.

"etc…"

George next to him was stunned for a moment:

"What about me?"

Lyles glanced at him:

"There's no part of this problem that you're good at, you're responsible for handling the paperwork while we move forward."

"When the final results are released, I want to see your calculation documentation simultaneously with the project files!"

After saying this in one breath, Lyles turned his attention back to the screen in front of him and took a deep breath.

Next, he is going to have a big fight!
