... rate and wall heat flux, are calculated and examined versus emerging rheological parameters and thermal relaxation time. Findings The thermal relaxation time measures the ability of a fluid to restore its original thermal state, called thermal equilibrium and therefore, simulations have shown...

...H.A. Machado; H.R.B. Orlande Solves the inverse problem of estimating the wall heat flux in a parallel plate channel, by using the conjugate gradient method with adjoint equation. The unknown heat flux is supposed to vary in time and along the channel flow direction. Examines the accuracy...
