“…Results from EDR were in harmony with experimental data. The proportional relationship between q" and NTU also resemble the effectiveness-NTU relationship interrelated report [19]. Note that this analysis was validated only for 1-1 pass arrangement with bounded 0.36 < NTU < 1.67.…”

Rapid evaluation for plate heat exchanger is vital in energy-intensive chemical epoxidation as plant shutdown is not always feasible. In this paper, critical parameters for three different sizes of plate heat exchanger were determined based on temperature assessment via infrared thermometer. Extent of fouling was determined based on values of overall heat transfer coefficient, U0. Number of heat transfer unit (NTU) larger than 1.25 and Nusselt (Nu) higher than 50 was found to be efficient and had sufficient degree of convection for epoxidation. Furthermore it was found that NTU had a significant and nonlinear relationship with heat flux, q" and Nusselt, Nu for the duration-sensitive epoxidation. However in this study, LMTD showed insignificant difference with respect to plate heat exchanger performance.

“…An early experimental and numerical study by Liu and Tsai [16] concluded that the laminar flow becomes turbulent flow for Reynolds numbers approximately greater than 300 in a cross-corrugated channel of small plate heat exchangers. Also, Focke et al [1] conducted the experiments to study the effects of the inclination angle on the hydraulic characteristics of corrugated channels.…”

Abstract. Research of devices for heat recovery is currently focused on increasing the heat effectiveness of plate heat exchangers. The goal of optimization is not only to increase the heat transfer but also reduce the pressure loss and material costs. During the optimization of plate heat exchangers using CFD, we are struggling with the problem of how to create a quality computational mesh inside complex and irregular channels. These channels are formed by combining individual plates or blades that are shaped by molding, vacuum forming, or similar technology. Creating computational mesh from the bottom up manually is time consuming and does not help later optimization. The paper presents a new method for creating of computational meshes to simulate flow and heat transfer in a plate heat exchanger. This method is based on dynamic mesh method "user defined deforming" provided by ANSYS Fluent. The method is fast and provide applicable tool for optimization. Influences of cell size and count of layers of computational cells on heat transfer and pressure drop were investigated. It was found that the minimum number of layers is twelve across the channel, otherwise obtained data can be irrelevant. IntroductionHeat exchangers belong to the main parts of each energy and thermal devices and systems. The main purpose of each heat exchanger is to transport heat energy from one warmer medium, such as gas, liquid or steam, into other colder medium. In recuperative heat exchangers, both media are separated by walls and the heat energy must transfer also through this material.The phenomena in heat exchanger are very complicated and include not only heat conduction in material, which separates both mediums, but also flow of both mediums and heat transfer from medium into material walls. The development of recuperative heat exchangers in recent years focused on increasing effectiveness, but others requirements must be fulfilled too. We will focus mainly on plate heat exchangers, in which both mediums are separated by plates, in this study.
