Numerical Study on Heat Transfer Enhancement of Laminar Flow through a Circular Tube with Artificial Rib RoughnessBy Suvanjan Bhattacharyya, Himadri Chattopadhyay, Samir Kumar Saha
Abstract: This work presents the configuration optimization of a typical square roughness in a circular tube for laminar heat transfer in air using computational fluid dynamics (CFD) modelling. Conjugate heat transfer 2D numerical model has been developed and successfully carried out. CFD numerical simulations were carried out to analyze the flow and heat transfer in the air duct of a solar air heater provided with rectangular ribs. The laminar flow model …
