Free convection heat transfer for an inclined steel pipe of 55⁰ was carried out for different heat inputs .The experiments were carried on specially developed facility to perform constant heat flux and the temperatures were measured by thermocouples. The electrical input to the heater was controlled by dimmer stat and is measured by wattmeter. The experiments are carried for Gr number; the effects of inclination and Gr number on the temperature distribution were investigated. The average

The aim of project was concentrated on optimizing the Design (D/L RATIO) of inclined heated steel pipe for different heat input. Further by using the boundary condition of different heat input flow of steel pipe, analysis for copper pipe is carried out through CFD and L/D ratio of inclined heated copper pipe for different heat input was finalized.
