| -2- The condensate was not weighed but the temperature was always high correspondingly to a density of about .965. To ensure the steam entering the condenser being dry it was superheated to 103-105°C. in a coil over a blowlamp. The temperatures at different points on the condenser were measured by thermocouples. The difference in temperature between the condenser and cooling water was small except for very large heat flows. Tests on Leading Edge Condensers. Sections 6 inches long (area .625 sq.ft.) were tested in a wind stream from the blower rig. To obtain as far as possible a two dimensional type of flow over the condenser section it was mounted between two 1/8" thick shaped wooden blocks between two large aluminium plates see drawing No.2. No attempt has yet been made to streamline the back or to test for different angles of incidence. The results are given in curves 3 & 4. No results could be obtained for low air-speeds on account of the unsteadiness at tick-over speeds of the engine used in the blower rig. Ha/T.P.de P. 6 Prints attached. | ||
