Cube convection cooling transfer
WebIn this archived presentation, we begin with a brief overview of the capabilities of COMSOL Multiphysics ® for modeling conduction, convection, and radiation; heat transfer in fluids; and surface-to-surface radiation.. Then, we share information about many of the … WebFor convection we use the convection heat transfer coefficient hc, W/(m 2 K). A different approach is to define h through the Nusselt number Nu, which is the ratio between the convective and the conductive heat transfer: = ˘ ˇˆ ˘ ˙˝ ˘ ˇˆ ˘ =(ℎ ∗˚)/! (2) Where: − Nu = Nusselt number − hc = convective heat transfer coefficient
