“…7 shows schematics of two distinct flow patterns occurring in the present cross-corrugated heat exchanger matrix. According to the previous literatures [11,12], as a summary, two distinctive flow patterns are induced by the configuration of the crosscorrugated surface in the heat exchanger matrix.

“…Doo et al [11,12] studied the parametric study of three types of novel surface geometries derived from the primary corrugated surface with a sinusoidal profile. The turbulent flow considered in their study was modeled by the low Reynolds number k-ε turbulence model based on the Reynoldsaveraged Navier-Stoke (RANS) equations.…”

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.

“…The results of an isotropic heat transfer model and those of an anisotropic transfer model were also compared in order to evaluate the analytic results, comparing conditions, such as the effects of varying inlet temperatures and the temperature difference between the hot side and cold side. Doo et al [4] studied an engine intercooler by calculating the analytic area where the channel-fin pitch was adjusted using the Navier-Stokes equation. Results were obtained using the dimensionless Nusselt number, the Stanton number and the entropy generation rate.…”

This paper presents the heat transfer and pressure drop characteristics of a primary surface heat exchanger (PSHE) with corrugated surfaces. The PSHE was experimentally investigated for a Reynolds number range of 156-921 under various flow conditions on the hot and cold sides. The inlet temperature of the hot side was maintained at 40˝C, while that of the cold side was maintained at 20˝C. A counterflow was used as it has a higher temperature proximity in comparison with a parallel flow. The heat transfer rate and pressure drop were measured for various Reynolds numbers on both the hot and cold sides of the PSHE, with the heat transfer coefficients for both sides computed using a modified Wilson plot method. Based on the results of the experiment, both Nusselt number and friction factor correlations were suggested for a PSHE with corrugated surfaces.
