Forced Convection in Wavy Microchannels Porous Media Using TiO2 and Al2O3-CU Nanoparticles in Water Base Fluids: Numerical Results

<p>  </p> <p>In the present work, attempt is made to investigate the performance of three fluid with forced convection in a wavy channel. The fluids are water, a nanofluid of 1%TiO₂ in a water solution and a hybrid fluid which consists of 1% Al₂O₃-Cu nanoparticles in a water solution. The wavy channel has a porous insert with a permeability of 10 PPI, 20 PPI and 40PPI respectively. Since Reynolds number is less than 1000, the flow is assumed laminar, Newtonian and steady state. Results revealed that wavy channel provides a better heat enhancement than a straight channel of the same dimension. Porous material increases heat extraction at the expenses of the pressure drop. The nanofluid of 1%TiO₂ water provided the highest performance evaluation criteria.</p>
