    摘要： A stator-rotor assembly is described, including at least one interface region and a gap between a surface of the stator and a surface of the rotor. The stator is a nozzle or vane that includes circumferential endwalls. Each endwall includes at least one leading edge and one trailing edge, relative to a hot gas flow path. A trailing edge of at least one of the endwalls includes a pattern of cavities that are capable of impeding the entry of hot gas into a wheelspace region that adjoins the gap between the stator and the rotor. The cavities can also be formed on various sections of the rotor. The stator-rotor assembly can be incorporated into various turbomachines, such as gas turbine engines. Related processes are also described.

    摘要： A multi-domain cooling assembly 100 configured to be coupled with one or more heat sources 104 includes a body 118 having an outer surface 102 and at least one cooling chamber 106, 114 disposed inside the body 118. The at least one cooling chamber 106, 114 extends in at least two orthogonal dimensions and includes a working fluid to extract thermal energy from the one or more heat sources 104. The assembly 100 includes a cooling channel 108 disposed within the body 118 and fluidly coupled with a passageway 110, 112 that carries cooling fluid into and out of the cooling channel 108. At least a portion of the cooling fluid is a liquid phase, a gas phase, or a liquid-gas mix phase. The cooling channel 108 is fluidly separate from the at least one cooling chamber 106, 114. The cooling channel 108 is thermally coupled with the at least one cooling chamber 106, 114. The at least one cooling chamber 106, 114 transfers thermal energy from the working fluid to the cooling fluid.
