∇⋅T = ρ(∂v/∂t + v⋅∇v)
The heat transfer is governed by the conservation of energy equation, which states that the rate of change of energy is equal to the sum of the heat added to the system and the work done on the system. The conservation of energy equation is expressed as: ∇⋅T = ρ(∂v/∂t + v⋅∇v) The heat transfer
where T is the stress tensor, ρ is the fluid density, v is the fluid velocity vector, and ∇ is the gradient operator. ρ is the fluid density
