Computational Fluid Dynamics predicts many fascinating fluid problems and conjectures for the behavior of solutions related to their flows characterized by conservation laws. The fundamental of all CFD problems are Navier-Stokes equations that describe fluid motion. Several analytical and numerical methods are designed to handle these coupled partial differential equations and describe physics behind their existence and applications. Advance learning in the field of fluid flow frames, their behavior and numerical simulations to achieve desired solutions, give opportunities to explore different areas related to flow control, reacting flows, planetary atmospheres and their instabilities. In recent years, modern nanotechnology has shown extreme potential of fluid flows subjected to given thermal environment using nanofluids. Micro and nanofluids technology are rapidly emerging because of numerous applications due to the nanoscale dimensions (nanorods, nanotubes, nanowires, nanosheets, nanocoolants etc.). Nanoparticles especially metal oxides (ZnO, MgO, etc.) with augmented thermal, rheological and energy transport properties enhance the efficiency of base fluids (water and ethylene glycol) and impact their flow regimes. The Prandtl number influence the thermal boundary layer, hence concludes the results of temperature profiles for a range of Prandtl number at low Reynolds number for incompressible laminar flow. The velocity profiles for pressure gradient parameter and volume fraction of nanoparticles are important to analyze.
