ESTIMATION OF THE TIMEWISE AND SPACEWISE VARIATION OF THE WALL HEAT FLUX TO A NON-NEWTONIAN FLUID IN A PARALLEL PLATE CHANNELDOI: 10.1615/ICHMT.1996.TransientConvHeatTransf.520 Humberto Araujo Machado AbstractIn this paper we apply the conjugate gradient method with adjoint equation to solve the inverse problem of estimating the unknown transient boundary heat flux, which is also supposed to vary along the flow direction, in a parallel plate channel. The physical problem involves the flow of a power-law fluid inside the channel. Simulated temperature measurements are used in the inverse analysis. The effects on the inverse problem solution of number and location of sensors, power-law index and random measurement errors are examined. |
