Heat transfer refers to the transfer of thermal energy from one body to another due to the temperature gradient. There are three modes of heat transfer: conduction, convection, and radiation. Conduction occurs due to the vibration of molecules, convection occurs due to the fluid motion, and radiation occurs due to the electromagnetic waves. Conduction occurs due to the vibration of molecules,
The mass transfer is governed by the conservation of mass equation, which states that the rate of change of mass is equal to the sum of the mass fluxes into and out of the system. The conservation of mass equation is expressed as: There are two types of mass transfer: diffusion
∂ρ/∂t + ∇⋅(ρv) = 0
Mass transfer refers to the transfer of mass from one phase to another due to the concentration gradient. There are two types of mass transfer: diffusion and convection. Diffusion occurs due to the random motion of molecules, while convection occurs due to the fluid motion.
The momentum transfer is governed by the conservation of momentum equation, which states that the rate of change of momentum is equal to the sum of the forces acting on the fluid element. The conservation of momentum equation is expressed as:
