High Operating Temperature Energy Systems Laboratory (HOTeS Lab)
The High Operating Temperature Energy Systems Laboratory (HOTeS Lab), located at the Department of Energy from the School of Mechanical Engineering (FEM) of the University of Campinas (UNICAMP), is dedicated to experimental and modelling studies associated with general thermal hydraulics, with focus on high-temperature advanced energy systems and use of advanced instrumentation, like distributed thermal sensing optical fiber. This includes liquid sodium heat pipes applied to solar and nuclear microreactor applications, advanced Triply Periodic Minimal Surface (TPMS) heat exchangers, Critical Heat Flux under PWR and BWR conditions, Flow boiling and condensation heat transfer and pressure drop, Two phase flows, Supercritical fluids heat transfer behavior, use of supercritical CO2 in closed Brayton cycles and heat exchangers, additively manufactured heat exchangers, modelling of thermal-power systems, Waste heat recovery in power plants, among others.
