RISAn Optimization Method for Valve Seat Contour to Improve the Sealing Performance of Cryogenic Butterfly Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Triple-offset butterfly valves are manufactured under standard temperature conditions. During cryogenic service, critical sealing structures undergo uneven deformation due to thermal contraction. This leads to ...
Efficient Model-Free Calibration of a 5-Degree of Freedom Hybrid Robot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pose accuracy is a crucial issue that limits the application of hybrid robots. The model-free calibration instead of complex error modeling is investigated to improve the pose accuracy of a 5-degrees-of-freedom (DOF) ...
Investigation on the Flow and Heat Transfer Characteristics in a Multi-Pass Channel Using Magnetic Resonance Velocimetry and Transient Thermochromic Liquid Crystal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The three-dimensional flow field in multi-pass channels with and without ribs was measured by magnetic resonance velocimetry (MRV), while heat transfer performance on the endwall of channels in the same geometry was ...
