Abstract In this work, heat transfer enhancement in a microchannel using water-Ag nanofluid has been investigated numerically by the lattice Boltzmann method (LBM) by adopting the stream and collide algorithm, with the (BGK) approximation. The base fluid and the suspended nanoparticles are considered as a homogeneous mixture. And single phase model with first order slip and jump boundary conditions has been adopted. Thermophysical properties of water-Ag nanofluid are estimated by the theoretical models. Effects of change in nanoparticle volume fractions, Reynolds number and Knudsen number are considered. It was concluded that change in nanoparticle volume fractions did not have significant effects… More >

Abstract Among primary and secondary school teachers in China, 70% of teachers believe facing more significant occupational pressure. 63.8% of teachers clearly stated that occupational stress had caused a tremendous impact on them. And this has had adverse effects on them, such as mental, physical, and personal development. This paper studies the group of public-funded regular students from the perspective of psychological support. This paper uses the SCL-90 form to investigate the professional psychology of teachers for the psychological support of public-funded regular students engaged in the teaching profession. And it conducts a survey on the curriculum setting and satisfaction of… More >
