title = "Impact of Yaw angle on the Effectiveness of an Air Curtain for Solar Cavity Receivers",
abstract = "An experimental study was performed to quantify the effectiveness of an air curtain through the direct measurement of the convective heat losses from a scaled-down heated cavity receiver (0.3 m ID, 0.45 m length and 0.1 m aperture) in a large wind tunnel. The tilt angle of the cavity was kept constant at 15° while the yaw angle changed from 0° to 45° and 90° for wind speeds of 0, 3, 6 and 9 m/s. A blowdown purpose-designed air curtain was used to establish an aerodynamic barrier across the aperture of the cavity. The velocity of the air curtain flow was changed from 4.5 to 9 and 18 m/s with two different discharge angles of 0° and 30°. The results show that a low velocity side-wind decreases the convective heat losses. It is also found that the application of the blowdown air curtain with a side wind (yaw angles of 45° and 90°) increases the convective heat losses by 2.7 times over the no air curtain case for these conditions.",
