WebJun 15, 2024 · The first laws is: ∂ e ∂ t + ∇ ⋅ ( e v) = T: ∇ v + ∇ ⋅ q − Q, where e is the energy density; v the velocity of the fluid or material; T is the stress, e.g. the pressure or viscosity in a fluid; q is the surface flux of heat, and Q is the volume sink of heat. WebJan 30, 2024 · The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances. Mathematically, this is represented as (1) Δ U = q + w with Δ U is the total change in internal energy of a system,
