In the context of design studies for the U.S. Large Blast/Thermal Simulator (LB/TS), a liquid-nitrogen (LN), pebble-bed evaporator and superheater was designed for the 1/6th-scale LB/TS Test Bed. This pebble-bed heater would produce hot nitrogen gas at a predetermined temperature from a cryogenic LN2 source at pressure up to 1700 psig. The flow rate would be sufficient to fill the driver tube of the BRL LB/TS Test Bed rapidly enough to minimize the heat losses through the uninsulated driver walls and to maintain the required nitrogen gas temperature.
