FVM method based on K − ε model to simulate the turbulent convection of nanofluid through the heat exchanger porous media

Heat transfer and thermodynamic analysis of the impact of porous media and nano‐powder types in an open cavity equipped with an electronic component

“…The advanced Brinkman Darcy-Forchheimer equations are used to account for the effects of porous media. 50 The governing equations based on the hypothesis above are as follows: Continuity equation Equation ( 1): ∂ ∂…”

“…The nanofluids' thermophysical characteristics are considered to remain constant. The advanced Brinkman Darcy–Forchheimer equations are used to account for the effects of porous media 50 …”

“…Heat transmission under turbulent conditions across partly porous channels was numerically examined by Nimvari et al 48 They regarded two common layouts of the channel's pore layer; center arrangement and border arrangement. On the other hand, using numerical methods, an examination of turbulent flow in an undulated channel partly filled with a porous layer was examined by Al‐Aabidy et al 49 Simulating turbulent convection in a heat exchanger using the k – ε model entails the use of the finite volume method was examined by Abu‑Hamdeh et al 50 They used ferrofluid as a working fluid with a magnetic field. They observed that the heat transmission decreases when the nanoparticle is suspended in the base fluid without a magnetic field.…”

“…Launder and Spalding [7] in 1974. e stability and high accuracy of the model make it the most widely used model at present [8]. is model obtains the solutions of k and ε by solving the k equation of turbulent kinetic energy and the turbulent dissipation rate ε equation, then calculates the turbulent viscosity with the values of k and ε, and finally obtains the solution of Reynolds stress through Boussinesq hypothesis [9].…”
