Flow and Heat Transfer in Narrow Channels with Corrugated Walls

Analysis of Heat Transfer, Friction Factor and Exergy Loss in Plate Heat Exchanger Using Fluent

“…The results of this study, presented in terms of friction factor, wall heat flux and heat transfer coefficients, are compared with the collected experimental data and suggest that the CFD code is capable of predicting the flow and heat transfer characteristics in this kind of complex geometries. It must be also noted that the limited results of relevant experimental and theoretical works reported in the literature are found to be in fairly good agreement with the results of this study, which is currently in progress [2,3]. In optimization of plate type heat exchanger, the objective function is to achieve a minimal total annual cost of heat exchangers to determine the optimal dimensions of the apparatus with the given conditions of equipments operation.…”

“…Application of this corrugated wall type equipment in industry is continuously increasing; the necessary knowledge for modeling and optimization of their performance is still limited. A commercial CFD code (CFX® 5.7) was used in References [2,3] to simulate the performance of a model heat exchanger comprising of equivalent flat plates, for both single pass parallel and counter flows. The CFD simulation is validated using experimental data on pressure drop and overall temperature differences acquired for counter current flow of water at both sides of the model heatexchanger for various hot fluid flow rates (corresponding to a Reynolds number range from 1500 to 2300).…”

The effects of geometrical parameters of a corrugated channel with in out-of-phase arrangement

“…Kanaris et al [11] studied numerically forced convection of water turbulent flow in a plate heat exchanger with undulated surface. It was shown that the optimal performance was achieved as the channel plates are coming closer to each other and for less obtuse (sharper) corrugations and using lower value of channel aspect ratio (wider channels).…”

Flow and Heat Transfer Prediction in a Corrugated Plate Heat Exchanger using a CFD Code

“…Efforts have already been made towards effective simulation of a PHE [8,15,16]. Due to the modular nature of a PHE, a common practice is to think of it as composed of a large number of Representative Element Units, RES (i.e., of unitary cells), and obtain results by using a single cell as the computational domain and imposing periodicity conditions across its boundaries.…”
