The present study focused on investigating jet impingement phenomenon using Eulerian Multiphase method. The Reynolds number and slot jet width are fixed as 10,000 and 5 mm. The separation distance (S/L) is fixed as 6 to achieve maximum heat transfer. The SiO2 − Water nanofluid is considered as working fluid. The SiO2 volume fraction in nanofluid is spanned as 0 − 3 %. The impingement surface is assumed as isothermal surface having temperature as 20 K higher than jet temperature. The solid phase flow modelling is implemented using Kinetic Theory of Granular Flow. The SiO2 volume fraction effect is investigated on nanofluid thermophysical properties and Thermo − Hydraulic parameters. The nanofluid thermal conductivity and solid viscosity shows enhancement with enhanced SiO2 volume fraction. However mixture viscosity may reduce/increase in different jet impingement region. The Thermo − Hydraulic parameter Enhancement Factor (EF) shows improvement with increasing SiO2 volume fraction indicating overall system efficiency improvement.
