Thus, problems were encountered control; however, gate valves have straight‐ Traditional gate valves generally performed with some conventional gate valves in the course through flow passages which offer an advantage reasonably well in such applications; at worst, a of tests required by 89‐10. ...
thermal stability were not problems when a unitary cast iron friction casting was used. Therefore, to use a polymeric material successfully, the problem was narrowed to finding a substitute material not only with better non-abrasive properties, or, stated differently, better lubricity, but with acce...

15). The material was assigned with the properties of C45 steel, and its model was described by Eq. (1). The material was preheated to 1100 °C, the temperature of the tools was maintained constant at 50 °C, the tool velocity was v = 300 mm/s, the friction factor was 0.95,...
The velocity field, temperature field, and concentration field along with skin friction and the Nusselt and Sherwood numbers were evaluated for numerous values of relevant parameters, such as unsteadiness parameter A, Casson fluid parameter b, wedge angle parameter 𝑚,m, magnetic parameters, porosity...

This segment of the work is committed to explore the outcomes of requisite factors for the water-based Ag-MgO hybrid nanofluid on velocity profile, temperature distribution, friction factor, and heat transfer for the solution of three different flow geometries (a flat plate, stagnation point, and...
The experiment is carried out using two wedge models with different dead-rise angles β. The two models are both 60 cm long and 20 cm wide, with a plate thickness of 3 mm. Owing to the presence of friction, the acceleration of the model is not equal to the acceleration of gravity. ...
4.2. Simulation Analysis of Critical Disengaging Speed In the overrunning state of the slanted support clutch, friction occurs between the outer ring and wedge before it is fully disengaged. The wedge accelerates to rotate in the same direction under the force of the outer ring. With an increase...
