It is found that the overall heat transfer coefficient of elliptic cylinder with k.0 is higher than that of a circular cylinder.At k=6.0,it has the maximum which is about 1.6 times that of a circular cylinder.At the same time,the drag coefficient drops down with the increase of k.For k=2.0,the drag coefficient is about 60％ that of a circular cylinder.
