1. A method of regulating pressure in a thermal transport bus of a gas turbine engine, the method comprising:
operating the gas turbine engine with the thermal transport bus having an intermediary heat exchange fluid flowing therethrough, the thermal transport bus including one or more heat source heat exchangers and one or more heat sink heat exchangers in thermal communication through the intermediary heat exchanger fluid; and
adjusting a flow volume of the thermal transport bus using a variable volume device in fluid communication with the thermal transport bus in response to a pressure change associated with the thermal transport bus;
wherein the variable volume device is configured to adjust the flow volume of the thermal transport bus by 2% to 20% of an initial flow volume of the thermal transport bus.
