ANALYSIS OF A V-SHAPED CHANNEL WITH INCLINED ANGLES

With the discrepancy of the inclined angle inside the horizontal V-shaped channel heat pipe, the curve of vapor-liquid interface among every channel must different. By vapor-liquid interface balanced stress, one can calculate the various curvature of vapor-liquid interface in different inclined angles and the volume flow rate. The dimensionless liquid flow shape factor and the maximum heat transport capacity in different inclined angle of the channel are presented. The influences of liquid mass, contact angle, half angle of channel and operating temperature are studied. The maximum heat transport capacity will be shown when incline angle psi=0. However, when the liquid level is lower and half angle is smaller, or the operating temperature is lower, the influences of inclined angle will become weaker. But the contact angle is smaller, the influences then of inclined angle will be stronger.
