Authors(3) :-Satish Kumar Aharwar, Dr. Ajay Singh , Ashish Verma

Working towards the goal of saving energies and to make compact the design for mechanical and chemical devices and plants, the enhancement of heat transfer is one of the key factors in design of various equipment’s such as heat exchangers, refrigerator, air-conditioner etc. In this process without application of external power we can enhance the heat transfer rate by modifying the design by providing the roughness in tubes. Various artificial roughness in tubes finds applications in automobile, aerospace, power plant and food industries due to certain advantages such as compact structure, larger heat transfer surface area and improved heat transfer capability. Nusselt number, friction factor, pumping power required and LMTD variation of flowing fluid with respect to Reynolds number is studied for different parameters. This paper describes complicated behavior of fluid flow and is captured for both the fluids flowing inside and outside the tube. From literature, it has been found that with increases in P/d ratio the Nusselt number will decrease and the outer wall boundary condition does not have any significant effect on the inner Nusselt number. The Darcy friction factor decreases with increase in Reynolds number. The Pumping power increases with increase in Reynolds number for all the condition of P/d ratio and for all the boundary conditions. The optimization point between Nu and pumping power with respect to Re; shifts toward the higher Reynolds number with increase in P/d ratio.
