... utilization (EU) and energy utilization ratio (EUR) for various operating parameters such as inlet air velocity, mass of paddy, temperature, a spiral, and cone angle are investigated. Similarly, the exergetic efficiency and the rate of exergy destruction are also studied for the same operating parameters...

... coflow velocity from left to right. When there is no air coflow ( U c = 0), the flames of each burner are identical to each other (Fig. 2( a ) ). This means that without a coflow, the cone angle has almost no effect on the structure of the flame. In this case, the flames attach to the burner...

... of Reynolds numbers of 4000–14,000 was analyzed. The heat exchange efficiency is a combination of the convective heat transfer and the overall heat recovery. The results of this study indicate that for a spiral-coil tube of length L, increasing the cone angle improves the convective heat transfer outside...
