Nowadays, to improve or to increase efficiency of heat transfer medium to another task is very difficult to find new method by using geometrical changes and some using the some external sources affected on heat transformation dimple surfaces in which the dimple is nothing but "hole" like or depression like structure in which air circulation is created and to help heat transfer more effectively, we create some shapes of dimple; and to this various shapes we compare with flat plate then we find some changes in our data. We can use various methods to identify which shape is more effective.
