RISQuasi-One-Dimensional Loss Model of Volute Using Boundary Layer Approach for Inward Flow Radial Supercritical CO2 Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inward flow radial sCO2 turbines operate at considerably higher speeds than conventional gas or steam turbines making only the low specific speed designs practically realizable. Low-specific speed designs suffer from ...
Effect of Fluid Barrier in See-Through Labyrinth Seal for Supercritical CO2 Turbomachinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Radial supercritical carbon dioxide (sCO2) turbomachinery is being explored as a viable option for a submegawatt (sub-MW) power generation. However, at these scales, parasitic losses arising from disk friction ...
Analytical Model for Leakage Prediction in an Axial Labyrinth Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Compact size and efficiency of a radial turbomachine make it a preferred choice for submegawatt (MW) scale supercritical CO2 (sCO2) power plants. At submegawatt power thresholds, mitigation of parasitic losses ...
Influence of Geometric Parameters for a 100 kW Inward Flow Radial Supercritical CO2 Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Highly compact and efficient design makes inward flow radial (IFR) turbine a preferred choice for kilowatt scale supercritical CO2 (sCO2) power blocks. The influence of geometric design parameters on sCO2 turbine performance ...
Effect of Blade Scalloping on Performance of Inward Radial Flow Supercritical CO2 Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Research on submegawatt supercritical CO2 (sCO2) power blocks featuring single inward flow radial (IFR) turbines has gained momentum on account of growing demand for waste heat recovery applications. A key challenge ...
Topology Optimization of Discontinuous Fin-Based Microchannel Heat Exchangers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The article provides the development of a multiobjective optimization function for designing discontinuous plate-fin microchannel heat exchangers (PFMCHEs). Stagnation pressure energy, thermal energy gain, and ...
