Abstract
The boiling process is used as an efficient and effective method of transferring heat between a surface with a higher temperature to a fluid with a lower temperature in contact with the surface. This process is widely used in industry because of its high heat transfer coefficient. In present article, The effect of groove number, depth and groove width on pure water boiling heat transfer coefficient at atmospheric pressure on grooved surfaces has been discussed, experimentally. The groove surfaces are made with wire cutting machine technology with a groove number of 2- 4- 6, groove width of 1- 2- 3 mm and channel depth of 1- 2- 3 mm. The results showed that for the grooved surfaces, the heat transfer coefficient was increased by 35%. also with increasing number of grooves, increasing channel depth and increasing groove width the heat transfer coefficient increased
