This study explores the thermal performance improvement of louvered-fin flat-tube car radiators using a hybrid nanofluid of Al2O3 and SiO2 nanoparticles in a water-ethylene glycol (50:50) mixture. Through detailed CFD simulations combined with symbolic regression. the research analyzes the impact of various air velocities and nanocoolant flow rates on heat transfer efficiency. pressur... https://www.nutritionesplus.shop/product-category/pet-supplies/
