Development of CFD Inverse Analysis Technology Targeting Heat or Concentration Performance by Using the Transient Adjoint Method and Its Application to the Actual Components

Abstract

A new Inverse Analysis Technology for CFD which can select heat or concentration performance as the cost function was developed. By adding the formulation of scalar transport and expanding the Adjoint variables to our own developed program and by improving the solution methodology, the calculation of the surface geometry sensitivity distribution with respect to the performance such as the amount of heat transfer or scalar component flow rate has become possible both for steady state and transient problems. Its validity and the effectiveness to the design of actual components were confirmed by applying it to the improvement of gas distribution performance of the engine intake system, etc.
