Abstract
Increased heat transfer has played a very important role in achieving significant cost and energy savings. Today's developments in science and technology are fueling the demand for exceptionally featured compact devices with the best performance, accurate functioning and long lifespan. As a consequence, researchers and scientists met to focus on the thermal management of heat transfer devices. Superior thermal transfer properties of solids compared to traditional fluids allowed the investigators to introduce a new type of fluids with a mixture that was eventually formulated and referred to as "nanofluids”. Nanofluids have made a significant contribution to the historically utilized heat transfer enriching methods, such as mini-channel assistance and expanded surfaces (fins). But most of the nanoparticles used are considered to be hazardous to humans and the environment. A significant research is therefore performed on bio-nanomaterials to which the atmosphere is inherently subjected. In this study, a numerical investigation into the heat transfer characteristics of mango bark nanofluids in a double pipe heat exchanger is carried out. As we know, Nowadays, CFD is applicable to many manufacturing and technological issues, and nano-fluid heat transfer efficiency is no exception. So to analyze the heat transfer physiognomies of a double pipe heat exchanger the simulating software ANSYS 16.0 were used. The main objectives of this research are to analyze the thermal efficiency of nano-fluid (Mango Bark-Water) relative to nano-fluid Al2O3-Water. Based on the results obtained by the CFD and the mathematical calculations, this is established; there are great prospects for the use of these Bio-nanofluids as heat transfer fluids it being superior to the base fluid in terms of heat transfer characteristics.
