Paper Details

The performance of any compressor is depends on many parameter like pressure, temperatureand application of compressor, The efficiency of compressor is mainly depends on heat generation andheat rejection from system, there are variety of heat exchanger used for heat removal like water cooler, aircooler, plate and bar, shell and tube etc. the present work is aim to focus on air-cooled performanceenhancement via fin design. The fin is one of the critical components of heat transfer proper design andlocation of fin on heat exchanger can improve a performance lots. The aim of work is to improve the heatexchange rate of current cooler without changing the parameters like air flow, air velocity. The variety offin like plain fin, circular fin, herringbone etc. will be verified against geometrical arrangement likecircular pitch, rectangular pitch, triangle pitch for performance enhancement and same can be variey withhelp of CFD. The new cooler fin design was suggested based on the Computational analysis of coolerwhich was indicating a circular fin with Al as a fin material will give us a better heat rejection and lowerpressure drop for cooling air flow. The cooler sample model of cooler was manufactured with help of heatexchanger manufacturer and the cooler performance was measured in industrial test setup having windtunnel the setup is having all the facilities to measure Velocity, temperature and pressure drop across thewind tunnel also the ambient air temperature can be vary with help of submerge heater and oil tank whichcan be precisely measured and controlled. The latter stage of work shows the comparisons of both resultsand we have observed the gap of near about 7.875 % in both results which is far enough to accept as perliterature review, the gap analysis was carried out to identify why the gap was observed in both case.
