Abstract: This work describes the use of deposition-based additive manufacturing (AM) techniques to fabricate air-cooled, two-fluid heat exchangers. The project focused on a Heating, Ventilation and Air Conditioning application and ...

Abstract: Supercritical carbon dioxide (SCO2) Brayton cycles have the potential to offer improved thermaltoelectric conversion efficiency for utility scale electricity production. These cycles have generated considerable interest ...

Abstract: The stability of a steam plume during direct-contact condensation into a crossflow of subcooled water is investigated for mass fluxes that are higher (>600 kg/m2s) and a nozzle diameter (2.4 mm) that is smaller than ...

Abstract: Supercritical CO2 (sCO2) is a promising working fluid for future highefficiency power conversion cycles. In order to develop these cycles, it is necessary to understand supercritical and twophase CO2 flow. This paper ...

Abstract: The supercritical carbon dioxide (sCO2) Brayton cycle is an attractive thermal cycle for compact power generation applications due to its high efficiency and power density. Hydrodynamic gas journal bearings are attractive ...

Abstract: The assembly of a two-dimensional (2D) nematic liquid crystal at an interface between two liquids can be exploited to assemble densely packed and highly aligned arrays of rod-like nanoparticles. This method is especially ...

Abstract: Instantaneous temperature measurements at the interface between a solid wall and a thin, unsteady liquid film are performed using thermoreflectance, a nonintrusive optical technique with high temporal resolution. A laser ...
