PHYSICAL EFFECTS OF VARIABLE FLUID PROPERTIES ON GASEOUS SLIP-FLOW THROUGH A MICRO-CHANNEL HEAT SINK

Physical effects induced in micro-convective gaseous slip-flow due to variation fluid properties are numerically examined this paper. The problem is particularly simulated for through a micro-channel heat sink (MCHS) having constant flux supplied from the wall under hydrodynamically and thermally fully developed flow (FDF) conditions. It observed that Nusselt number (Nu) significantly higher than no-slip-flow condition Nu affected variable (VFP). Four different cases of VFP studied order investigate their individually. Pressure temperature dependent density (ρ(p, T)) flattens axial velocity profile radial direction (u(r)) which promotes faster-moving particles close considerably enhances Nu. incorporation temperature-dependent viscosity (μ(T)) marginally along flow. Incorporation thermal conductivity (k(T)) highly augments ρ k near specific at pressure (Cp(T)) reduces lower wall. investigation also shows drop deviates no-slip slip condition. Furthermore, on gauge static (Δpg) examined. μ(T) k(T) variations trivially affects Δpg velocity. However, Cp(T)
