WebbThe laminar flow-forced convection of Al 2 O 3-water nanofluids in a square cross-section duct subjected to a constant heat flux was numerically studied. The results show that the heat transfer coefficient and Nusselt number increase with an increasing Peclet number and particle volume concentration. WebbLaminar flow is defined as a parallel flow of molcules in a pipe, whereby the transverse distribution of the speed of the molecules is parabolic. ... but reducing the …
WebbIn the region of the boundary layer most distant from the surface, flow is turbulent and mass transfer is the result of the interchange of large portions of the fluid. Mass … WebbFör 1 dag sedan · Laminar flow is like a deceptive peace but problematic in future, sometimes we need going to meet turbulent flow in life , still i prefer laminar Like Reply Jodie Jinnette Director of...
