Experimental Analysis of Heat Transfer and Friction Factor in a Roughened Solar Air Heater using Staggered Inclined Discrete Rib Arrangement
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 4
Abstract
The solar air conditioner (SAH) utilizes barbell roughness to improve heat transfer. Experimental evaluations are complete on friction factor and the heat transfer in the retina, and this is sometimes roughened from the ribs that were probable. The ribs were discretized by making a gap at distinct positions (not in line) on tracking and top edge in consecutive ribs (in a staggered arrangement). The rib roughness has relative roughness pitch since 8.0, rib mix of comparative gap positions is varied from 0.3 & 0.1 to 0.3 & 0.4 and mass flow rate varies from 3000 to 14000 and rib relative gap width as 1.0. The increased advancement in Nusselt number is obtained in 2.62 times together with the friction factor is obtained in 2.91 times, respectively, in contrast to a smooth duct. Maximum thermohydraulic performance (THP) parameters are renowned for its own rib combined relative gap rank of 0.3 and 0.3.
