T1 EXTENDED GRAETZ PROBLEM WITH BRINKMAN EXTENSION FOR LAMINAR VISCOUS FLOW IN ANNULI JF Heat Transfer Research JO HTR YR 2019 FD 2018-10-26 VO 50 IS 2 SP 107 OP 123 K1 extended Graetz problem K1 viscous flow K1 laminar flow K1 analytical solution K1 annuli AB The Fourier method is used to solve the extended Graetz problem for laminar flow in annuli by including the effects of axial conduction in both the upstream and the downstream directions. The exact solution is obtained under unequal constant wall temperatures and including the effects of viscous dissipation. The results are compared with other well-known data. The eigenvalues and asymptotic Nusselt numbers are derived as a function of the geometric characteristic and Peclet number as parameters.
