(PDF) Comparison of Heat Transfer between a Helical and

Helical pipes are universally used for heat transfer enhancement in heat exchangers. In the present work, CFD simulations are carried out for a counter flow double pipe helical heat exchanger by (PDF) INTENSIFICATION OF HEAT TRANSFER AND FLOW IN This article presents an experimental study on enhancement of heat transfer and pressure drop of nanofluids flow. In this study the method using to enhancement of heat transfer and pressure drop, by used the helically coiled tube heat exchange and

18. 5 Heat Exchangers The general function of a heat exchanger is to transfer heat from one fluid to another. The basic component of a heat exchanger can be viewed as a tube with one fluid running through it and another fluid flowing by on the outside. A Presentation on Heat Exchanger - Make Piping EasyThe spiral type heat exchanger is manufactured by rolling two metal plates around a central core to generate two concentric spiral flow passages, one for each fluid. The plate edges are welded in a manner so that each fluid stays within its own passage and there is no bypass flow CFD Analysis of Double Pipe Counter Flow Heat ExchangerCFD Analysis of Double Pipe Counter Flow Heat Exchanger Dhrubajyoti Bhattacherjee Department of Mechanical Engineering, Swami Vivekananda Institute of Science & Technology. Abstract:-The design of a double pipe in tube heat exchanger has been facing a problems because of

DESIGN AND FABRICATION OF HELICAL TUBE IN COIL TYPE

Oct 02, 2015 · The results of the helical tube heat exchanger are compared with the straight tube heat exchanger in both parallel and counter flow by varying parameters like temperature, flow rate of cold water and number of turns of helical coil.

The measured data are totally optimised utilizing thermodynamics rules in which exergy study is performed to investigate the thermal performance of the helical system under different operating conditions. Heat Exchanger FundamentalsCounter flow heat exchangers are the most efficient of the three types. In contrast to the parallel flow heat exchanger, the counter flow heat exchanger can have the hottest cold-fluid temperature greater than the coldest hot-fluid temperatue.

Heat transfer analysis of a straight tube and helical coil

Apr 30, 2017 · Amol S. Niphade [3] has done a CFD analysis of a shell and tube heat exchanger used in dairy industries for getting pasteurised high volume of milk in a short span of time. Dr. B. Jayachandraiah [4] has designed a helical coil heat exchanger and has analysed it using CFD at varying volume flow rates 40, 60, 80, 100 and 140 LPH at Coil side and Tube-in-tube heat exchangers - Alfa Laval - heat transfer The new Alfa Laval Tube-in-tube heat exchanger is specifically designed for sludge which contains fibres and particles, making it ideal for heating and cooling of most wastewater sludge. The equipment consists of a single tube mounted inside an outer shell tube, so that the product medium flows counter-current through the inner tube, with the Alfa Laval spiral heat exchangers4 Alfa Laval spiral heat exchangers Alfa Laval spiral heat exchangers (SHEs) are based on an ingen-ious design. It provides optimum heat transfer and flow conditions for a wide variety of fluids, with a built-in self-cleaning effect, while keeping the overall size of the unit to a minimum.
