Abstract In this paper, a new approach called the Eulerian species method was proposed for simulating the convective and/or boiling heat transfer of nanofluids. The movement of nanoparticles in nanofluids is tracked by the species transport equation, and the boiling process of nanofluids is computed by the Eulerian multiphase method coupled with the RPI boiling model. The validity of the species transport equation for simulating nanoparticles movement was verified by conducting a simulation of nanofluids convective heat transfer. Simulation results of boiling heat transfer of nanofluids were obtained by using the commercial CFD software ANSYS Fluent More >

Abstract A high-order numerical model is developed to simulate species transport for use in emergency response situations. The model includes employing an hp-adaptive finite element technique to construct velocity fields within complex geometries as well as over irregular terrain features. Lagrangian particles are used to display contaminant dispersion patterns. The use of hp-adaptive finite element methods permit both automatic local refinement and unrefinement of the computational grid - a fine mesh is developed in those regions where flow features and/or species gradients change rapidly while a coarse mesh is employed where flow and transport are unvarying More >
