Abstract

The present study investigated the influence of variable viscosity of temperature dependent fluids on the laminar heat transfer and friction factor in a 2:1 rectangular duct. The present numerical results of local Nusselt numbers for oil showed 70 - 80% enhancement over those of a constant property fluid and 40 -50% enhancement over water, and gave excellent agreement with recent experimental results. The heat transfer enhancement from the heated top wall was due to an increased velocity gradient near the wall. A new correlation for local Nusselt numbers in the 2:1 rectangular duct was proposed which covered both thermally developing and thermally fully developed regions. Consequently, a temperature-dependent viscous fluid together with a non-circular duct is proposed to be used in the design of a liquid cooling module for the computer industry and in compact heat exchangers in general.
