COMPARATIVE STUDY OF THERMAL CHARACTERISTICS OF METALLIC AND NONMETALLIC WATER-BASED NANOFLUIDS IN A SQUARE CAVITY

Heat transfer fluids are a dynamic factor that affects the costs and size of heat exchangers. However, low thermal properties accessible coolants like water oils place setback on growth to attain high-performance cooling. The paper presents numerical analysis comparative study characteristics Al 2 O 3 , CuO, AlN, SiC water-based nanofluids in square cavity. cavity is surrounded by hot moving horizontal plate, an adiabatic vertical wall right, left lower sides cold isothermal walls. governing equations were solved using finite approximation techniques assess four different enclosure with varying sizes nanoparticles range 1% ≤ φ 10%. results reveal CuO has pattern compared other nanofluids. highest Nusselt number 58.4715, least value 58.4634 at 10 % volume fraction. Nanoparticle substantial influence attributes This work indicates have satisfactory than based fluid water, which determines its applications.
