Mathematical Modeling of flow and heat Transport characteristics of Nano fluid through a disc

Abstract

Nano uids have sparked considerable interest in engineering circles for their boosted newline thermal and uidic characteristics, gaining traction in diverse applications in recent newline years. Nano uids, which are made up of nanoparticles suspended in a base uid, have newline very di erent heat transfer and rheological properties than regular uids. Among the newline myriad applications, the study of nano uid ow over rotating discs holds particular newline importance in the elds of thermal management, aerospace propulsion, and industrial newline processes. Rotating discs are ubiquitous in engineering systems, employed in centrifugal newline pumps, gas turbines, and disc brakes, among others. Understanding the behavior of newline nano uid ow over rotating discs is crucial for optimizing the performance and e ciency newline of such systems. When the rotating disc and nano uid ow interact, complicated uid newline dynamics e ects happen, such as the formation of boundary layers, improved heat transfer, newline and ow separation. Moreover, the presence of nanoparticles in the base uid further newline alters the ow characteristics, o ering opportunities for enhancing heat transfer rates and newline reducing frictional losses. The major goal of this thesis is to examine the Newtonian and newline non-Newtonian nano uid ow through the rotating disc with the presence of Cattaneo newlineChristov heat ux model, Joule heating newline
