Resumo

This paper deals with the use of the conjugate gradient method of function estimation for the simultaneous identification of the boundary heat fluxes at the vertical walls of a rectangular cavity. The physical problem involves transient two-dimensional laminar natural convection inside the cavity and the functions are estimated with no a priori information regarding its functional form. The accuracy of the present inverse problem approach is examined by using simulated temperature measurements containing random errors. The effects of the number and location of temperature sensors on the inverse problem solution are also addressed in the paper.
