Microparticle suspensions are prevalent in both natural and industrial environments, playing a crucial role various processes. The heat transfer characteristics between particles fluids critical to many of these This study employs the Arbitrary Lagrangian-Eulerian finite element method simulate analyze particle dynamics fluid–solid within microchannel, aiming determine based on average temperature particles. effects five factors (particle thermal conductivity, specific capacity, fluid Reynolds number, diameter, initial position) were comparatively analyzed. results indicate that laminar microchannel reach self-equilibrium position under combined action shear gradient wall lift force, with size being primary influencing factor. effect causes rotate, thereby enhancing convective fluid. number also significantly impacts this process. Additionally, heat, size, can influence by altering internal distribution particle. We derived an expression for Nusselt using dimensionless analysis method, which describes microparticle.
