Transport Phenomena Cluster

Important Information for Proposers

A revised version of the NSF Proposal & Award Policies & Procedures Guide (PAPPG) (NSF 22-1), is effective for proposals submitted, or due, on or after October 4, 2021. Please be advised that, depending on the specified due date, the guidelines contained in NSF 22-1 may apply to proposals submitted in response to this funding opportunity.


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.
