Fluid flow consideration in fin-tube heat exchanger optimization

Fin-and-Tube Heat Exchanger Solid Core Advanced Simulation

This paper is devoted to the presentation of an advanced model for the heat conduction processes within a finned tube bundle, typically found in air-cooled evaporators and condensers. As a result of the computational effort needed to simulate the desired fin-and-tube local unsteadiness, some actions have been undertaken in order to obtain reasonable simulation time consumption. A specific cutti...

Thermoeconomic Lifecycle Cost Optimization of an Annular Fin Heat Exchanger

In this paper the design of annular fin heat exchanger based on economic optimization has been carried out. The optimization process targeted minimizing the lifecycle cost of annular fin heat exchanger that has the same frontal area, effectiveness and heat load of available practical standard geometry exchangers. The lifecycle cost includes both capital and operating costs. Beside the pumping c...

Effective Heat Transfer Enhancement in Finned Tube Heat Exchanger with Different Fin Profiles

During cross flow in a heat exchanger, heat transfer in the front portion of the tube is more compared to back portion of the tube. This is due to less formation of vortices at the backside of the tube. For uniform heat transfer to take place throughout the tube, it is necessary to increase the vortex formation at the rear side of the tube. The aim of this study is to explore the possibilities ...

Enhancement of Round Tube and Flat Tube-Louver Fin Heat Exchanger Performance Using Deluge Water Cooling

An experimental study has been conducted to evaluate the performance of a compact round-tube louver-fin condenser, each with frontal areas of 0.25 m in both dry and wet conditions. Deluge water cooling is achieved by incorporating a perforated bottom plate-type water distributor on top of the round tube heat exchanger. Water is used as a refrigerant, and enters the heat exchanger tubes at 35°C ...
