Plate-Fin Heat Exchanger Application ID: 109881 This tutorial model shows how a plate-fin heat exchanger made of aluminum is used to cool down hot oil with colder air. The heat exchanger is constructed by stacking several pleated sheets or plates on top of each other while leaving a gap between them. Several design parameters and operating conditions influence the optimal performance of a shell and A double-pipe heat exchanger consists of two concentric pipes often performing a U-turn. A square cross-section is used for the fluid channels instead of circular Abstract: Heat exchangers are used widely in many industries for heat recovery or cooling purposes. The heating fluid circulates in the gaps This model solves the fluid flow and heat transfer in a micro heat exchanger made of stainless steel. Several design parameters and operating conditions influence the optimal Borehole Heat Exchanger Application ID: 19545 This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. Figure 1 shows the heat exchanger’s geometry. For a description of that application, including detailed step-by-step instructions showing how to build it, see Double-Pipe Heat Exchanger. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. This is a great solution for functions of high level of sophistication on energetic systems. Kindly watch first video using this link : • HOW TO MODEL SHELL AND HEAT EXCHANGER The Non isothermal Flow predefined multiphysics coupling is configured with the turbulence model in this A double-pipe heat exchanger consists of two concentric pipes often performing a U-turn. The heat exchanger is made of high tensile steel (Steel AISI 4340). MatLab® and COMSOL integration increases capacity of GA and offers a new optimization process for COMSOL. This tutorial model shows how a plate-fin heat exchanger made of aluminum is used to cool down hot oil with colder air. ). Aug 21, 2014 · Using COMSOL Multiphysics, we analyze temperature changes within a coil heat exchanger. No-slip condition gives continuity in heat flux and temperature at the fluid-solid interface There is a continuity in temperature over the solid-fluid interface. The heat exchanger itself is constructed by stacking several pleated sheets or plates on top of each other while leaving a gap in between. In this application, two For heat exchanger we could maximize heat flux obtaining different geometric dimension with good results. This example studies the cooling of hot oil (130°C) by a cool oil (60°C) entering in counter-current. The BHEs are simplified as line heat sinks with a uniform heat extraction rate. Double-pipe heat exchangers, with their typical U-turn shape, are one of the simplest and cheapest type of heat exchangers used in the chemical process industry. However, because the unit cells are identical except for edge effects in the outer cells, you can restrict the model to a single Optimizing Heat Exchanger Designs for Refrigeration and Cooling Technology Cooling an indoor ski slope, providing air conditioning to a prestigious old castle, or chilling and freezing consumer goods — these scenarios all require heat exchanger technology.

A square cross-section is used for the fluid channels instead of circular Learn how to build a model of a shell-and-tube heat exchanger to accurately study the heat transfer coefficient and pressure drops. However, because the unit cells are identical except for edge effects in the outer cells, you can restrict the model to a single Why Heat Transfer is Important to Modeling The Heat Transfer Module is an optional package that extends the COMSOL Multiphysics modeling environment with customized physics interfaces and functionality optimized for the analysis of heat transfer. The main purpose of this tutorial is to show the basic principles for setting up a heat exchanger model. Additionally, they can be found in many engines and are used to cool hydraulic fluid and oil. In this model, two separated fluids at different temperatures flow through the heat exchanger: one through the tubes (tube side) and the other through the shell around the tubes (shell side).
