Abstract: | The present research compares traditionally used straight fin cylinder block of 150 newlineCubic Centimetre four-stroke IC engines with the same size wavy cylinder block. For newlinethis research work, experimentation was carried out at machine lab of Government newlineEngineering College Bhuj, Kachchh, Gujarat. First of all, the numbers of samples newlineanalysis of wavy fin were carried out in CFD using CFX 17, for the getting optimized newlinewavy fin design. The wavy fin cylinder block of optimized design and conventional newlinestraight fin cylinder block were modelled in solid works and numerical analysis were newlinecarried out by using ANSYS software for conjugated heat transfer flow for force newlineconvection between 0 km/hr to 80 km/ph. For experimental investigation and newlinecomparison the optimized wavy fin design cylinder block of same size and material as newlineconventional straight fin block was manufactured from LM2 Material by VMC newlinemachine and all the blocks were experimentally investigated for their heat transfer newlineperformance in wind tunnel for 0 km/hr to 80 km/hr speed. The results found from the newlinetesting show improved performance of wavy fin in comparison to the straight fins for newlinethe same purpose. Also further experimentation was done to check the effect on heat newlinetransfer coefficient by alternatively using of different fin configuration like supporting newlineribs, porous ribs, and adding slots on two and four sides of the wavy cylinder block. newlineThe comparative results indicate the deviation between numerical and experimental newlinedata and this is due to CFD error and also present research experimental data are newlinebetter or giving good agreements with past researchers data. |
