This Project Grant award from the National Science Foundation (CFDA 47.041 - Engineering) provides $710,741 to The Pennsylvania State University to investigate the fundamental differences in how heat and momentum are transferred to and from rough surfaces in turbulent air and water flows. The research team will use experiments in water and glycerin tunnels as well as high-fidelity computer simulations to study the detailed behavior of turbulent flow and heat transfer near complex roughness patterns. The objective is to explain the physical differences between momentum and scalar (e.g., thermal) transport in rough-wall turbulent flows, with the hypothesis that momentum exchange is governed by unsheltered windward surface areas while scalar transfer depends on unsheltered planar surfaces. The research will support improvements in weather modeling, pollutant dispersion, heat exchanger design, and even blood flow in roughened vessels. The project will also provide hands-on research experience for graduate students, support STEM education, and launch a public podcast series to communicate the science and its relevance to society. The award period is from July 1, 2025 to June 30, 2028.
