![]() ![]() This is why Nirmala and Otanicar’s plan to use mixed particles of two particular sizes will reduce these voids, make the particles more snug, and enable heat to transfer more fluidly. Otanicar explained that a current limitation with using solid particles in heat exchanger beds is that the voids between particles makes it difficult to move heat in and out of the exchanger. This is primarily due to low cost and elimination of freezing concerns seen with molten salts,” said Otanicar. “Research and commercial interest in solid particles as a means to store and transport high temperature thermal energy has increased significantly over the last few years. ![]() The team however intends to use cost-effective particles commonly used in fracking. Fluids are not ideal mediums because they are susceptible to freezing, and can also be costly. To improve the performance of CSP, Otanicar and Kandadai are breaking away from the industry norm of using fluids such as molten salts in the heat exchangers in order to discover if solid particles of two different sizes in packed beds can be even more effective. ![]() Second, the development of a new technique to measure near wall heat transfer.” Nirmala Kandadai “First, is to enable a significant increase in particle heat transfer properties that enables the next generation of concentrating solar power and thermal energy storage. “Our hopes for this research are two-fold,” said Otanicar. competitiveness in manufacturing, improve grid reliability, and tackle emerging challenges in the solar industry. The team was awarded $260,000 for a year in order to investigate a novel method to increase the thermal conductivity in heat exchangers, and hopefully improve the performance of concentrating solar power (CSP) plants.Īccording to the Solar Energy Technologies Office website, the Solar Energy Technologies Office Small Innovative Projects in Solar (SIPS) funds research projects that advance early-stage solar technologies to reduce the cost of solar, increase U.S. Department of Energy Solar Energy Technologies Office for 2020 (SETO 2020) funding. Boise State associate professor of mechanical and biomedical engineering Todd Otanicar and assistant professor of electrical engineering Nirmala Kandadai were selected by the U.S. ![]()
