Abstract
In fluid dynamics, CFD(ComputionaI Fluid Dynamics) and measurements hava been used for estimating flow fields. However, CFD has inevitably errors accompanied by boundary condition, discretization and numerical calculation, and measurements include missing data and some errors involving their methods. In this study, cost function which consists of errors of basic equations and of errors measured data was proposed to correct measurements using governing equations in room heat environment and understand both flow and scalar field accurately. As a result, it was confirmed that Cost Function Method is effective to estimate velocity and temperature if boundaiy condition is settled improperly in CFD.
