“…Many numerical and experimental studies on the forced convection flow in a wavy channels using conventional fluids are available in the literature [1][2][3][4][5][6][7][8]. These studies showed that the heat transfer rate increased but there is also increase in friction factor as a compared with the results of straight channels.…”

“…These studies showed that the heat transfer rate increased but there is also increase in friction factor as a compared with the results of straight channels. On other hand, the convective heat transfer of nanofluid in channels has been numerically and experimentally investigated by many researchers [1][2][3][4][5][6][7][8][9][10][11][12][13]. Laminar forced convection of copper-water nanofluid in straight channel was numerically studied by Santra et al [14].…”

a b s t r a c tIn this paper, laminar forced convection flow of Al 2 O 3 -water nanofluid in sinusoidal-wavy channel is numerically studied. The two-dimensional governing equations of continuity, momentum and energy equations in body-fitted coordinates are solved using finite volume method. The sinusoidal-wavy channel with four different phase shifts of 01, 451, 901 and 1801 are considered in this study. The results of numerical solution are obtained for Reynolds number and nanoparticle volume fractions ranges of 100-800 and 0-5%, respectively. The effect of phase shift, nanoparticle volume fraction and Reynolds number on the streamline and temperature contours, local Nusselt number, local skin friction coefficient, average Nusselt number, non-dimensional pressure drop and thermalhydraulic performance factor have been presented and analyzed. Results indicate that the optimal performance is achieved by 01 phase shift channel over the ranges of Reynolds number and nanoparticles volume fractions.

In this article, laminar convective heat transfer of copper-water nanofluid in isothermally heated wavy -wall channel is numerically investigated. The governing continuity, momentum and energy equations in body-fitted coordinates are discretized using finite volume approach and solved iteratively using SIMPLE algorithm. The study covers Reynolds number and nanoparticle volume concentration in the ranges of 100-800 and 0-5 % respectively. The effects of nanoparticles volume concentration and Reynolds number on velocity and temperature profiles, the local Nusselt number, the local skin-friction coefficient, average Nusselt number, pumping power and heat transfer enhancement are presented and analyzed. Results show that there is a significant enhancement in heat transfer by addition of nanoparticles. This enhancement increase with concentration of particles but the required pumping power also increases. The present results display a good agreement with the literature.

Study on the turbulence model sensitivity for various cross-corrugated surfaces applied to matrix type heat exchanger

Diverse cross-corrugated surface geometries were considered to estimate the sensitivity of four variants of k-ε turbulence models (Low Reynolds, standard, RNG and realizable models). The cross-corrugated surfaces considered in this study are a conventional sinusoidal shape and two different asymmetric shapes. The numerical simulations using the steady incompressible Reynolds-averaged NavierStokes (RANS) equations were carried out to obtain the steady solutions of the flow and thermal fields in the unitary cell of the heat exchanger matrix. In addition, the experimental test for the measurement of local convective heat transfer coefficients on the heat transfer surfaces was performed by means of the Transient liquid crystal (TLC) technique in order to compare the numerical results with the measured data. The features on detailed flow structure and corresponding heat transfer in the unitary cell of the matrix type heat exchanger are compared and analyzed against four different turbulence models considered in this study.
