The objective of this study is investigate heat transfer performance and flow development in three different corrugated channel using different rib shapes (Trapezoidal, Triangle and semicircular), a numerical simulations were carried out for uniform
plate heat exchanger with corrugation angle 30º assumes an approximate parabolic shape and that for a corrugation angle of 60º the profile have a irregular core. Simulations considering and discarding the influence of temperature on the non-Newtonian fluid viscosity were performed for the two geometries and the impact of these
Heat transfer and exergy analysis of solar air heater tube Sep 15, 2020 · Experiments have been performed for different combinations of geometric parameters, such as corrugation angle () = 30° and 60°, corrugation pitch ratio (y) = 0.7 and 1.0, perforation ratio (k) = 0.16, 0.25, and 0.33, and perforated disc pitch ratio (s) = 1.5 and 2.5.
Jul 30, 2021 · In order to get more extensive information about the significance of the different geometry parameters on the efficiency of the heat exchanger, we simulated 30 different geometries
Influence of corrugation shape on heat transfer Mar 01, 2019 · According to this model, the modelled transport equations for k and are formulated as follows :(4) x j ( k u j) = x j [( + t k) k x j] + G k + G b + S k (5) x j ( u j) = x j [( + t ) x j] + C 1 S C 2 2 k + + C 1 k C 3 G b + S where:C 1 = max (0.43, / ( + 5)); = S k / ; S r = 2 S i j S i j; S i j = 1 2 ( u i x j + u j x i); G k = u i
Jun 01, 2002 · The main geometrical parameters of such structures are the inclination angle , the wavelength , the amplitude a and the shape of the corrugation. The effect of different geometrical parameters of these corrugated structures on the local and integral heat and mass transfer are discussed. It is shown, that the flow phenomena caused by the
