Our Solutions & Services

Numerical Simulations

We apply advanced numerical simulation technologies accumulated in natural science fields such as hydraulic engineering, combustion engineering, heat transfer engineering, and space engineering to financial engineering to provide solutions to support corporate strategies. In numerical simulation service, we introduce advanced numerical analysis technology which becomes the source of our financial business.

Overview of Services

We have accumulated technologies related to various numerical simulations through cooperative relationship with Tokyo Gas Technology Research Institute extending over 20 years. We mainly conduct commissioned calculations, and have experience in combustion related field and living environment such as gas industrial furnace, nuclear power, plant piping related field, construction field, etc. In recent years, we have also analyzed the flow inside the solid rocket motor of Japan's H-ⅡA rockets.

Commissioned analysis services

After being provided with materials by customers, we conduct various analyses such as hydraulic analyses and structural analyses. Finally, we submit a report.
The computing environment uses 64-bit Windows cluster machines. (Usage example: In hydraulic analyses, 3D calculation of several million cells)

Resident analysis service

Because the analysis subjects are often highly confidential, the data can sometimes not be taken out of the company. In these cases, when the customer has a suitable analysis environment, staff from our company will conduct the analysis work inside the customer's company.

Case Studies

Rocket engine combustion chamber simulations

These consisted of the visualization of the static temperature distribution and the wall heat flux distribution inside the small-sized combustion chamber of a liquid fuel rocket. Because the combustion in the critical state was the target, extremely advanced analysis technology was required.

Emission simulations inside experimental fuel tanks

These were simulations targeting the emission testing from a fuel tank, in which the water emission condition was shown. In order to simulate the conditions during flight, there were also cases of simulations executed where the emission speeds were changed in a time series and where the tank was tilted.

Rocket nozzle simulations

These were simulations targeting the nozzle part of a solid rocket motor, in which the flow of alumina was shown. Although the shape was different from that of the actual part, we simulate the influence made on the nozzle wall of the alumina which is present in the combustion flow.

Burner simulations

This consisted of the visualization of the flows inside a complex-shaped burner.
For complex-shaped burners, shape optimization is possible by simulating combustion with consideration of mixed state of fuel / oxidizer and chemical reaction. Regarding gas burner simulation, we have vast experience from low speed burner to supersonic burner.

Industrial furnace simulations

These simulations showed the temperature distribution inside furnaces.
Starting with the temperature distribution inside the furnace, by looking at the energy input amount with regard to the object that is being heated, it is possible to investigate factors such as the burner arrangement to equalize the energy input amount. Additionally, we have conducted many simulations according to the required purposes, including understanding the current situation and optimizing the burner arrangements.

Waste incinerating furnace simulations

These simulations showed the speed vectors and temperature contours in stoker-type waste incinerating furnaces.
Regarding waste incinerating furnaces, it is possible to execute valuation simulations in the case of using technology known as re-burning (secondary combustion) which is maintained by Tokyo Gas.

Indoor air conditioning simulations

These simulations showed the streamlines from air conditioners inside a room. Because Tokyo Gas also maintains many types of equipment relating to indoor environments including floor heating and bathroom dryers, we have many results relating to simulations of this equipment and its use.

Urban area dispersion simulations

These simulations showed the degree of the effect exerted on the surroundings by the exhaust from cogeneration facilities in an urban area where cogeneration facilities had been made. With regard to the dispersion simulations, a variety of simulations can also be conducted in various situations.
