Author(s): Kamlesh Kumari Sharma, Rahul Kumar, Kajal Sarmah
Abstract: Thermo physical properties like Re, Nu, heat transfer coefficient are experimentally simulated in this work for circular pipe. The work is preformed on water and Nano-fluid for same circular pipe, which is made of Cu material. The length of pipe is 600 mm having 21 mm diameter. Thickness is 1 mm of pipe. Inserts are applied to circular tube to increase its heat transfer coefficient during flow conditions. Total 16 experiments are designed for present study using Taguchi method. Different type of Model equation is generated for the present work and experimental validation is also preformed for present work. The thermal properties of Nano-fluid are solved using correlation equations for present study. Three design cases are generated for experimental studies which are following, first are simple tube, second are simple insert and last are twisted insert. The experimental analysis is performed for transient modeling environment. Mass flow rate and Pressure outlet boundary conditions are applied to inflow and outflow.
