Research ArticleOpen accessIn the abstractSimulation Studies on A Cross Flow Plate Fin Heat ExchangerM. Thirumarimurugan, T. Kannadasan, E. RamasamyCompact heat exchangers which were initially developed for the aerospace industries in the 1940s have been considerably improved in the past few years. The main reasons for the good performance of compact heat exchangers are their special design which includes turbulent which in turn use high heat transfer coefficient and resists fouling, and maximum temperature driving force between the hot … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,239 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNumerical Study of the Temperature Separation in the Ranque-Hilsch Vortex TubeSaeid Akhesmeh, Nader Pourmahmoud, Hasan SedgiThis research has been carried out in order to provide an understanding of the physical behaviors of the flow variation of pressure and temperature in a vortex tube. A computational fluid dynamics model is used to predict the flow fields and the associated temperature separation within a Ranque-Hilsch vortex tube. The CFD model is a steady axisymmetric model (with swirl) … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,316 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerformance Analysis of Shell and Tube Heat Exchanger Using Miscible SystemM. Thirumarimurugan, T. Kannadasan, E. RamasamyAn experimental investigation on comparative heat transfer study on a solvent and solution were made using 1-1 Shell and Tube Heat Exchanger. Steam is the hot fluid, whereas Water and Acetic acid-Water miscible solution serves as cold fluid. A series of runs were made between steam and water, steam and Acetic acid solution. In addition to, the volume fraction of … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 8,368 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Internal Flow Patterns on Heat transfer Performance of a Closed-end Oscillating Heat Pipe at Vertical PositionS. Rittidech, L. Yodluk, K. SongsornThis article describes the effects of varying bond numbers (Bo) and aspect ratios (Le/d) on flow pattern of a close-end oscillating heat-pipe (CEOHP). The CEOHPs used employed a glass tube with inside diameter of 3 mm. The length of evaporator of 100 and 150 mm (the lengths of evaporator adiabatic and condenser section were equal) were employed with 10 turns. … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,062 accessesView PDF Cite
