| General note |
Heat transfer enhancement has always been an issue that has plagued the scientific<br/>corridors for decades. Various techniques have been adopted using both active and passage<br/>techniques to reduce the thermal resistance and supplement the heat efficiency. Annular<br/>passages are one of the most commonly used in various industries and engineering systems<br/>due to their simplistic geometry and compact size. Efficiency of such systems have always<br/>been a keen point of interests for researchers and have resulted in advancements that have<br/>resulted in superior heat transfer as compared to primitive methods.<br/>One such advancement has been the introduction of nanofluids in limited concentrations<br/>with a base fluid to circumvent the limitations of the usual fluids used in the annular<br/>passages. A research gap exists in usage of Trihybrid Nanofluids in the annular passages<br/>which greatly enhances the heat transfer while providing greater thermal conductivity,<br/>improved flow and minimal thermal resistance. My research aims to study the effects of<br/>Tri hybrid nanofluids in two different types of annular passage ways (Circular and<br/>Diamond Shape) with inner and outer heating for 4 different Tri hybrid Nano fluids which<br/>are Al2O3, CuO and Fe3O4, Al2O3, TiO2, and SiO2, SWCNT, MWCNT, and TiO2, SiO2,<br/>TiO2, and ZnO, Gr, Ag, and TiO2 , CuO, MgO, and MWCNTs, all of which had a<br/>volumetric concentration of 3 percent and were suspended in water. The effectiveness of<br/>these tri hybrid Nano fluids was gauged by several factors which include calculation of<br/>Nusselt Number, hydraulic performance quantified by pressure drop whilst the heat<br/>transfer from the surface is calibrated by the heat transfer coefficient. An increase of 19.92<br/>% for Nusselt number was observed for TiO2, SiO2, TiO2, and ZnO but the pressure drop<br/>was way too high. In order to study the confluence of these factors a performance<br/>coefficient index was computed through which a tri hybrid Nano fluid (Al2O3, TiO2, and<br/>SiO2) was selected to be coupled with longitudinal vortex generators. The vortex generators<br/>are to be applied at various pitch angles mainly at 20,30 and 40 degrees and tested for all<br/>the performance parameters. |
