Based on the digital twin technology, this article investigates physical rules fusion model of turbine rotor operation in thermal power plants, establishes geometric behavior mapping method virtual scenario and develops a real-time data-driven monitoring system operation, which realizes control process from levels, respectively. The 3D created by Creo was imported into ADAMS x_t format, constra...

Liquivac pumps, with their unique shaped twin start helical rotor, have found utility in various sectors but the major drawback limiting global exploitation is low performance. This paper investigates study of performance pump produced by Tomlinson Hall Ltd. Experimental data was used to validate a numerical model developed Ansys Fluent 20.2 for pump. Four different geometric models rotor were ...

This paper presents the results of comparisons among some patented solutions for profiling contours rotors in twin-screw compressors. Referring to a base case where all generating curves are circumferences, patents suggesting replace arcs circumference with conic sections, i.e. parabola, ellipse and hyperbola, but even straight line segment, presented guidelines rotor profile construction repor...
