Abstract
A thermoacoustic engine-driven system with a hot heat exchanger, a regenerator or stack, and an ambient heat exchanger includes a side branch load for rapid stopping and starting, the side branch load being attached to a location in the thermoacoustic system having a nonzero oscillating pressure and comprising a valve, a flow resistor, and a tank connected in series. The system is rapidly stopped simply by opening the valve and rapidly started by closing the valve.

In a thermoacoustic engine-driven system with a hot heat exchanger, a regenerator or stack, and an ambient heat exchanger, a side branch load for rapid stopping and starting, the side branch load being attached to a location in the thermoacoustic system having a nonzero oscillating pressure and comprising a valve, a flow resistor, and a tank connected in series.
A method for rapid stopping and starting of a thermoacoustic engine-driven system including:
- attaching to a location of nonzero oscillating pressure of the thermoacoustic engine-driven system a side branch load comprising a valve, flow resistor, and a tank connected in series;
- opening the valve to stop the system and closing the valve to start the system.
