Abstract

Thus far, no research has inversely solved for boundary convective heat fluxes in indoor environments. This study proposed an inverse method based on Tikhonov regularization and least-squares optimization using computational fluid dynamics(CFD) to determine the wall boundary convective heat fluxes in indoor environments. The inverse model applied the CRI to establish a matrix to describe the cause-effect relation between the cabin wall boundary heat flux and the exhibited discrete temperature at certain points. To test and evaluate the proposed inverse model, it inversely solved the surface heat fluxes on walls in a three dimensional ventilation cavity and an office in a building. The RMS errors of the model were less than 80%. This study finds that the developed inverse method can accurately and efficiently determine the wall convective heat fluxes in indoor environments.
