Thermal Design of Cooling and Dehumidifying Coils
cdn.intechopen.comh mass = convective mass transfer coefficient, kg/m2 h fg = latent heat of vaporization, J/kg Since the transport mechanism that controls the convective heat transfer between air and water also controls the moisture transfer between air and water, there exists a relation between heat and mass tr ansfer coefficients, h C and h D as discussed in ...
Engine Heat Transfer - MIT
web.mit.edu3. Convective heat transfer depends on gas temperature, heat transfer coefficient, which depends on charge motion, and transfer area, which depends on flame/combustion chamber geometry 4. Radiative heat transfer is smaller than convective one, and it is only significant in diesel engines 27

We already have encountered the mass transfer coefficient, defined in a manner analogous to the heat transfer coefficient. It is a parameter that is used to describe the ratio between the actual
Convective Mass Transfer - Clarkson University
web2.clarkson.eduheat, and mass transfer from Section 28.6 of the textbook by Welty et al. (3). As we noted, the analogy between heat and mass transfer is good only when mass transfer occurs in a dilute system in which the role of convection caused by diffusion is negligible.
