Experimental Investigation of Condensation Heat Transfer Characteristics of R-134a Vapor in Horizontal Heat Exchanger

Experimental Study On R-134A Condensation Heat Transfer Characteristics In Plate And Shell Heat Exchangers

In this study, condensation heat transfer experiments were conducted with two types of plate and shell heat exchangers (P&SHE) using R-134A. An experimental refrigerant loop has been established to measure the condensation heat transfer coefficient of R-134A in a vertical P&SHE. Two vertical counter flow channels were formed in the P&SHE by stacking three plates of geometry with a corrugated tr...

An experimental investigation of heat transfer of Fe2O3/Water nanofluid in a double pipe heat exchanger

One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...

Experimental Study on R-410A Condensation Heat Transfer and Pressure Drop Characteristics in Oblong Shell and Plate Heat Exchanger

The Overall Heat Transfer Characteristics of a Double Pipe Heat Exchanger: Comparison of Experimental Data with Predictions of Standard Correlations

The single-phase flow and thermal performance of a double pipe heat exchanger are examined by experimental methods. The working fluid is water at atmospheric pressure. Temperature measurements at the inlet and outlet of the two streams and also at an intermediate point half way between the inlet and outlet is made, using copper-constantan thermocouple wires. Mass flow rates for each stream are ...
