The Transport Phenomena Cluster (TPC) consists of four programs that support fundamental investigations in science and engineering. The main themes of the cluster are single- and multi-phase flow dynamics, particulate, heat and mass transfer, and combustion and fire dynamics. All these themes share, at a fundamental level, the transport of mass, species, momentum and energy. Other more specific themes for TPC include turbulence and transition, biofluids, micro-fluids, flow instabilities, multiphase flows, particle dynamics, colloidal solutions, interfacial transport, combustion science, fire prevention and suppression, convention/diffusion/radiation, thermodynamics, bio-heat and mass transport, and micro-thermodynamics.
