Thermal stresses due to long running of spark ignition engine often results in wear and tear of cylinder near the top dead center (TDC). These high thermal stresses at TDC arise due to the high temperature gradient during spark ignition. This situation eventually decreases the life and efficiency of an engine. In this study, the numerical and analytical analysis was carried out on 1298 cc in line four stroke spark ignition (SI) engine having a power output of 63 kW to drop the peak temperature at TDC. to reduce the peak value of temperature, square pin fins were used on the surface of engine cylinder wall near TDC. A parametric study is performed to get an optimal solution for removal of the peak temperature load at TDC. The results showed that the fins with dimension of 4 × 4 × 4 mm3 along with uniform spacing of 2 mm provide the optimum solution. It has been observed that the peak temperature at TDC dropped down considerably from 160 °C to 133 °C (a percentage reduction of 16.87%) for the pin fins case as compared to without the fin case. Furthermore, the heat transfer effectiveness for the optimum case was calculated as 3.32, whereas for numerical and analytical study it was calculated as 3.43. The error recorded between both the values was limited to 3.2%.

The combination of nano fluid and changing cross-section mini-channel heat sink effects have become a remarkable choice for the use of thermal devices such as miniature electronic devices to be effectively cooled. In this paper, the comparison of three dimensional straight and wavy channel configuration with using different types nano fluids are numerically investigated. The effects of wave amplitude and A particular type of volume fraction of (Copper Oxide CuO, Dimond Al2O3, Iron Oxide Fe3O4, Titanium Oxide TiO2 and Silver Ag-nano fluids are offered. Three amplitudes of waves (0.15 mm, 0.2 mm and 0.25 mm) and Reynold’s number from 200 to 1000 and concentration volume varieties from 0 to 0.075 are used. The effect on thermal resistance, pressures drop, factor of friction of the mini channel is displayed. It is observed that the mini-channel sink's heat transfer efficiency is greatly enhanced compared to the straight channel in an event of adding distilled water as accoolant. The results indicate that nano fluid and wavy mini-channel can boost the heat sink's hydrothermal efficiency and Ag- water nano fluid in term of heat transfer, it outperforms other nanofluids an enhancement in the Nusselt number reached to 54% at concentration volume 0.075.

“…Mini‐channel heat sinks are an excellent alternative for cooling efficiently the high heat fluxes such as those taken place in the HCPV systems due to their increased convective heat transfer rate and medium heat drop. A mini‐channel heat sink was investigated numerically to study the effect of a slab thickness for microprocessor cooling 32 . The incorporation of slab thicknesses ranging from 0.2 to 1.6 mm in the mini‐channel heat sink reduced heat transfer while increasing the base temperature and pressure drop.…”
