Microgravity experiments with a simple two-phase thermal system are described. Microgravity experiments aboard the NASA KC-135 aircraft provide variable acceleration 0.01g to 2g, with low gravity for 20 to 25 seconds. The two-phase loop allows the vapor and liquid phases to flow together between the evaporator and the condenser. It incorporates and evaporator where heat transfer is controlled by forced convection, an adiabatic transport section where transparent piping provides visualization of the flow regime, and a condenser where heat transfer is controlled by the shear between the gas and liquid phases. Stable operation of the system is observed during the variable accleration.
