Derive the steady flow energy equation
WebIn such a system, the mass flow through the system is conserved (mass inside the system is constant if the flow is steady), so on the basis of per unit mass then Eq. 18 becomes (19) which is a common form of the … WebThe Steady Flow Energy Equation: The steady flow energy equation exists in two forms; both closely related to one another. The first form applies to compressible (variable density) flow, used in thermodynamics; The second form applies to incompressible (constant density0 fluid flow, used in fluid dynamics

WebJan 21, 2024 · Your observation is correct. For steady irrotational flow of an incompressible, inviscid fluid with constant density, the Euler equation of momentum reduces to $$\nabla \left(\frac{p}{\rho} + \frac{1}{2} \mathbf{u} ^2 + \chi \right) = 0$$ Integrating the components with respect to the spatial variables, we get the general solution WebStagnation temperature can be derived from the First Law of Thermodynamics. Applying the Steady Flow Energy Equation [2] and ignoring the work, heat and gravitational potential energy terms, we have: where: mass-specific stagnation (or total) enthalpy at a stagnation point
