Innovative Numerical Simulation Technology

Innovative Numerical Simulation Technology

Numerical simulation technology provides a environment for virtual experiments on computers. This technology is strongly expected as a powerful tool which can dramatically reduce a number of man-hour and cost for performing large-scale experiments and significantly make progress in performance of equipments.


We focus on three topics listed below.

1.
Deeply understanding phenomena (Analysis and modeling)
2.
Prediction of performance (Assessment and optimization of design and operating conditions)
3.
Development of simulation codes

Deeply understanding phenomena (Analysis and modeling)

A virtual experiment is performed by a numerical method which is more accurate rather than an experiment in order to observe phenomena taking place on the computer in detail. New findings are modeled and applied to a further complex field. A number of phenomena of which model has not been well established remains in the actual flow field on the equipment of thermal power plant.


Research topics:turbulent flows, coal combustion/gasification, spray combustion, tar decomposition, soot formation, NOx formation, etc.


Prediction of performance (Assessment and optimization of design and operating conditions)

Performance of equipments which are under designing and operating is evaluated examining effects of shapes and operating conditions in order to optimize design and operating conditions.


Research topics: coal-fired boiler, coal gasifier, GT blades, etc.


Development of simulation codes

A simulation program which can compute flow fields on large-scale complex-shaped equipments in a thermal power plant is developed by CRIEPI.
