Abstract: A method for nitrous decomposition can include: expanding liquid nitrous into gaseous nitrous in a decomposition chamber; injecting heated nitrogen gas into the decomposition chamber so as to mix with the gaseous nitrous, wherein the heated nitrogen gas is at a nitrous decomposition temperature; heating the gaseous nitrous with the heated nitrogen gas to the nitrous decomposition temperature; and decomposing the gaseous nitrous into nitrogen and oxygen. The method can include: heating the nitrogen to at least the nitrous decomposition temperature; heating the liquid nitrous prior to expansion into the decomposition chamber; and performing the decomposition without a catalyst or heating element in the decomposition chamber. A swirling device can be positioned at an inlet to the decomposition chamber. A swirling nozzle can be positioned at an inlet to the decomposition chamber.

Abstract: A method of power generation is provided that uses one or more structures made of zirconium tungstate in a convection fluid that rise or fall with temperature to create a reverse convection current cycle. The method can include heating the one or more zirconium tungstate structures to cause a decrease in volume and sink in the convection fluid. The method can include cooling the one or more zirconium tungstate structures to cause an increase in volume and rise in the convection fluid. The method includes generating power from the reverse convection current cycle.

Abstract: A variable 3D CD nozzle includes: a flexible body defining a flow path having an inlet extending through a narrowed throat to an expanded outlet, wherein the flexible body comprises a plurality of flexible members movably interconnected together; and at least one means for changing a shape of the flexible body to change a dimension or location of the throat plane relative to at least one of the inlet plane or outlet plane. A method of changing airflow in a nozzle includes operating at least one means for changing the shape of the flexible nozzle body to change the dimension or the location of the throat plane. A method of testing an object includes placing a test object in the test region of the test cell and passing a test gas from the outlet opening of the nozzle onto the test object.
