Abstract

Heat transfer in pipe flow is one of the wide applications that are used in industry. Among the various applications used in industry, heat exchangers are one of the most widely used applications. The principle of heat exchangers is to allow the heat transfer between any two fluids without physical contact between them having different temperatures. In saving energy and material resources in industry, heat transfer rise plays a vital role. Because of saving energy and material resources in industry, there is a need of design of compact heat exchangers that has low weight and high performance. To obtain more compact and efficient units enhanced surfaces are successfully used in the heat transfer industry. Due to simple fabrication and effective heat transfer enhancement, now day’s grooved tubes are widely used in the industry. The use of grooved tubes is found in evaporated condensers for saline water distillation, steam turbine power. In this study the forced convection heat transfer characteristics from grooved tube is investigated experimentally. The effect of variation in pitch of groove on heat transfer characteristics is investigated with variation in mass flow rate of air and heat input. Additionally the effect of variation in pitch of groove on pressure drop across test section is investigated with variation in mass flow rate of air and heat input. Whole experimentation has been carried out under turbulent flow condition.

Keywords: Thermal performance; Grooves Tubes; Forced Convection, Heat transfer coefficient.
