The high heat transfer rate achieved in flame impingement technique makes it suitable for various industrial heating operations which demands rapid heating. The geometric parameters of flame jet impingement has significant effect on heat transfer rate. One of these parameters is h/d (h is distance between flame emission nozzle and base plate while d is diameter of nozzle) which has significant effect on heat transfer rate. The current research investigates the effect of this geometric parameter i.e., h/d using techniques of Computational Fluid Dynamics. The CAD model of flame jet computational domain of different h/d ratio (1.2, 1.6, 2, and 2.4) is developed in Creo design software and CFD analysis is conducted using ANSYS CFX software package. Eddy dissipation model is used for combustion modelling and RNG k-epsilon model is used for turbulence. The temperature plot and heat flux plot generated from analysis predicted heat transfer rate at stagnation point
