Development of efficient computational codes and their technological applications

With the advances in computer technology and development of computational codes for fluid dynamics, solving complex equations has become mainstream. However, there is room for improvement in computational accuracy and time. For example, simulation of combustion in turbulent flows needs to solve hundreds of chemical equations simultaneously, which leads to a huge computational load. Therefore, efficient computational methods are required. In our laboratory, we are developing efficient computational codes for analyzing flow around fixed physical objects (Eulerien method) and as well as flow around moving physical objects (Lagrangian method). 
In addition to the development of efficient computational codes, we are working on application of these codes to technological studies such as “noise-reduction of turbulent flow from jet nozzle,” “development of micro gas turbine,” “development of artificial heart with magnetically suspended impeller,” and “flow analysis of moving animals as swimming fishes and flying birds.”
  • An example of computational code for the Lagrangian method combined with the thermal equilibrium method. With this code, accurate calculation is possible without using hundreds of chemical equations.
