TRUST is a thermohydraulic software package for CFD simulations. It was originally designed for incompressible single-phase and Low Mach Number flows, but now also allows simulating real compressible multi-phase flows. TRUST is also being progressively ported to support GPU acceleration (NVidia/AMD). This software is OpenSource (BSD license).
