Abstract

The vortex sink rate sensor device consists basically of an ideal sink flow between two coaxial disks. A sink tube was located at the center of one disk. The vortex was created by the rotation of the unit about its axis of symmetry. Five inch and 10 inch diameter of porous couplers were used for the air chamber here in this investigation. Several slenderness parameters, i.e., the ratio of the sink tube diameter to the height of the air chamber ro/n were conducted. Two probes were used to measure the static pressure and stagnation pressure respectively at various positions in the sink region. The data obtained was evaluated and plotted by the computer in terms of tangential velocity component as a function of the radial positions at two flow rates and several rates of rotation.

The results showed that the tangential velocity component in the sink tube region was affected by the geometric size of the porous coupler. The tangential velocity component increases with an increase in the diameter of coupler. For a maximum tangential velocity in the sink tube region, there may exist an optimum value of the slenderness parameter (ro/n).

The results also indicated that the tangential velocity increased with an increase in the rate of rotation and only slightly increased with the flow rate doubled from Q = 3.164 to Q = 6.328.
