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.
∇⋅T = ρ(∂v/∂t + v⋅∇v)
where c_p is the specific heat capacity, T is the temperature, k is the thermal conductivity, and Q is the heat source term. Mass transfer refers to the transfer of mass
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: ∇⋅T = ρ(∂v/∂t + v⋅∇v) where c_p is
Momentum, heat, and mass transfer are three fundamental transport phenomena that occur in various engineering fields, including chemical, mechanical, aerospace, and environmental engineering. The study of these transport phenomena is crucial in designing and optimizing various engineering systems, such as heat exchangers, reactors, and separation units. The study of these transport phenomena is crucial
The turbulence is governed by the Navier-Stokes equations, which describe the motion of a fluid. However, the Navier-Stokes equations are nonlinear and difficult to solve for turbulent flows.
