In this work, the performance study of an automobile radiator using nanofluid in comparison with distilled water as coolant in the heat exchanger-based radiator is evaluated. The distilled water and nanofluid are flown through the radiator consisting of upright tubes with an elliptical-shaped cross section. Forced air is passed through the radiator perpendicular to the direction of fluid flow in tubes. The experiments are performed with three different volumetric concentrations of nanofluid (Al 2 O 3-water), with different flow rates, air flow velocities, and fluid inlet temperatures. The results obtained from this study demonstrate that an increase in fluid flow rate and air flow rate improves the heat transfer performance. It was found that an enhancement in heat transfer rate was found to be the maximum up to 44.29% at 0.2% volume fraction of alumina-distilled water-based nanofluid in comparison with distilled water. The effectiveness of radiator was found maximum up to 40.3% at 0.2% volume fraction of alumina-distilled water based nanofluid at 40 LPH.

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%.

Due to high heat flux generation inside microprocessors, water-cooled heat sinks have gained special attention. For the durability of the microprocessor, this generated flux should be effectively removed. The effective thermal management of high-processing devices is now becoming popular due to high heat flux generation. Heat removal plays a significant role in the longer operation and better performance of heat sinks. In this work, to tackle the heat generation issues, a slotted fin minichannel heat sink (SFMCHS) was investigated by modifying a conventional straight integral fin minichannel heat sink (SIFMCHS). SFMCHSs with fin spacings of 0.5 mm, 1 mm, and 1.5 mm were numerically studied. The numerical results were then compared with SIFMCHSs present in the literature. The base temperatures recorded for two slots per fin minichannel heat sink (SPFMCHS), with 0.5 mm, 1 mm, and 1.5 mm fin spacings, were 42.81 °C, 46.36 °C, and 48.86 °C, respectively, at 1 LPM. The reductions in base temperature achieved with two SPFMCHSs were 9.20 %, 8.74 %, and 7.39% for 0.5 mm, 1 mm, and 1.5 mm fin spacings, respectively, as compared to SIFMCHSs reported in the literature. The reductions in base temperature noted for three SPFMCHSs were 8.53%, 9.05%, and 5.95% for 0.5 mm, 1 mm, and 1.5 mm fin spacings, respectively, at 1 LPM, as compared to SIFMCHSs reported in the literature. In terms of heat transfer performance, the base temperature and thermal resistance of the 0.5 mm-spaced SPFMCHS is better compared to 1 mm and 1.5 mm fin spacings. The uniform temperature distribution at the base of the heat sink was observed in all cases solved in current work.
