Description
Summary:The paper presents a comparative analysis on the laminar convective heat transfer characteristics of a 2-D flow over three different grooved profiles. The profiles selected for this study are trapezoidal, triangular and sinusoidal. The numerical simulation is performed using ANSYS-FLUENT SOLVER to elucidate the effect of changing fluidic properties over these channels in the Reynolds number range of 400-1400. The analysis is performed using two different fluids namely water and SYLTHERM 800 to present the changing thermal and fluidic behavior among the channels having fixed length and ribs. The influences of these profiles on pressure drop, streamline contours, temperature variations and entropy variations are discussed in details over these fluids, more over the results are presented in a comparative manner. The Governing equations are discretized using Finite Volume Method (FVM) and SIMPLE Algorithm along with Second Order Upwind Difference Scheme. When SYLTHERM 800 is passed through these channels in the given Reynolds number range it is observed that the trapezoidal channel has minimum decrement in entropy followed by sinusoidal and triangular channels for this flow conditions. Also, when we compared the results obtained using SYLTHERM 800 with traditional fluid i.e., water, then it is observed that there is more pressure drop, heat dissipation and entropy generation in case of SYLTHERM 800. The outcomes obtained in this work will further contemplate researchers to design various devices and systems with better thermal efficiency for various engineering and household applications.
