Correlation of Engine Cooling System Parameters and Segmented Heat Exchangers’ Analysis

Analysis of Supercritical Carbon Dioxide Heat Exchangers in Cooling Process

Full Analysis of Low Finned Tube Heat Exchangers

In this paper, first the governing parameters characterizing low-finned tubes are reviewed. Second, the more important of the available performance correlations are compared with the available experimental data. The most reliable one can be employed to develop a pressure drop relationship, which has already been used in an algorithm for exchanger sizing. Also a means for the identification of a...

Heat transfer and rheology of stirred yoghurt during cooling in plate heat exchangers

In the present work an experimental investigation was conducted to obtain a correlation for the determination of convective heat transfer coefficients of stirred yoghurt in a plate heat exchanger. A rheological study was carried out in order to characterise the stirred yoghurt flow behaviour, evaluating its dependency both on shear rate and temperature. A shift in the temperature dependency was...

ASSESSING THE EFFECT OF BLOCKAGE OF DIRT ON ENGINE RADIATOR IN THE ENGINE COOLING SYSTEM

This thesis looked at the effect of clay and silt soil blocking the heat transfer area of the radiator and its effect on the engine coolant through the conduct of experiments and a mathematical model developed. The results indicated that the percentage area covered resulted in a proportional increase of the inlet and outlet temperatures of the coolant in the radiator. The mathematically mode...

Analysis of Fouling in HVAC Heat Exchangers by CFD

The purpose of this study is to identify parameters influence on the particle deposition within fin and tube heat exchanger of air-conditioning systems by CFD analysis. First the basic sketch of periodic geometry drawn and meshing operation including boundary conditions was performed. Then the gas side properties and flow parameters were solved by ANSYS Fluent 14.5 software. Lagrangian equa...
