Wind velocities at various locations around hills for the distances between two conical shaped hills having the same height of 100m, that is, 2m, 20m, 40m, 60m and 140m, are estimated using computational fluid dynamics(CFD) analysis. Wind velocities obtained for the two hills are compared with those obtained for one hill as well as a plain. Compared with wind velocities for a plain, for the distances between two hills, that is, 2m, 20m, 40m, 60m and 140m, wind velocity between two hills at the height of 3m was increased by about 37%, 23%, 16%, 11% and 4%, respectively. In the case that the distance between two hills was 2m, the rate of wind speed-up at 3m above ground at the midpoint between two hills was about two times larger than that of the case of one hill. When the distance between two hills was 140m, the rate of wind speed-up was less than 5% at 3m above ground at the midpoint between two hills. Also, at the midpoint between two hills and at the foot of a hill in the crosswind direction, the rate of wind speed-up was less than 5% above 230m above ground. It was found from the study that the closer the distance between two hills, the larger wind velocity between two hills and at the foot of a hill by channeling effect.
