The entropy generation due to steady laminar forced convection fluid flow through parallel plates microchannel is investigated numerically. The effect of Knudsen, Reynolds, Prandtl, Eckert numbers and the nondimensional temperature difference on entropy generation within the microchannel is discussed. The fraction of the entropy generation due to heat(More)
This study is focused on the entropy production due to laminar forced convection in the entrance region of a concentric cylindrical annulus. The present hydrodynamic and temperature fields are obtained numerically. Local entropy generation distributions are obtained based on the resulting velocity and temperature fields by solving the entropy generation(More)
BACKGROUND Cancer of the biliary tract has a poor prognosis and its association with pregnancy is uncommon. Early diagnosis allowing curative surgical resection offers the only hope of long-term survival. CASE This report describes the case of a young 26-week-pregnant woman admitted for cholestatis documented by clinical and laboratory examination.(More)
