The right-angled constrained channel with square-section is a typical channel configuration in many engineering fields. However, due to the high curvature of the right-angled constrained channel, the flow field parameters are not uniformly distributed, which has an adverse effect on resource utilization or reaction efficiency of the industrial process. To address the above matters, the modeling and solving method for impinging disturbance-based flow field regulation are proposed to regulate the flow field distribution. According to the design criteria of the disturbance channel, a numerical model of impinging disturbance is set up based on the mixture multiphase model and realizable [Formula: see text] turbulence model. And the pressure–velocity coupling solution strategies are conducted to quickly solve the impinging disturbance mechanism. The distribution law of the flow field parameters at different disturbance velocities is obtained to reveal the turbulence variation mechanism caused by impinging disturbance. These research results show that the disturbance vortex produced by the collision between the disturbance flow and the mainstream can affect the parameter distribution characteristics of the flow field in the constrained channel together with the backflow vortex, dean vortex, and the secondary vortex. The disturbance flow can effectively interfere with or control the vortex structure and indirectly regulate the flow field parameters to improve uniformity and energy utilization by actively regulating the disturbance velocity.

With the continuous development of the coal mining industry in recent years, major mine accidents caused by colliery flood emerge in endlessly in China. Therefore, mine flood has been one of the bottlenecks restricting to China's exploitation of resources and large submersible pump is the only effective equipment for the prevention and rescue in mine-flood accident. Based on the BQW50 mine pump, this paper presented a new-type explosion-proof submersible mine pump with inner motor, and put forward the explosion-proof design, structural design and hydraulic design of mine pump. In addition, three-dimension unsteady turbulent flow calculations were implemented for this mine pump, and the strain caused by water pressure in the volute could be obtained by using the elastic finite element method for non-steady-state. Moreover, through the iterative coupled calculations between the fluid mechanics and solid mechanics, coupled analyses in the volute with the material of QT600-3 were obtained. The results indicate that the maximum stress appears at the junction between the volute tongue and the cover plate while the maximal strain comes out in the front cover plate in front of the volute tongue. In the case of normal working conditions, the resonance caused by the pressure pulsation appears unlikely. This paper is instructive to the proper design on the mine pump.

A mathematical model is presented to analyse the flow characteristics and heat transfer aspects of a heated Newtonian viscous fluid with single wall carbon nanotubes inside a vertical duct having elliptic cross section and sinusoidally fluctuating walls. Exact mathematical computations are performed to get temperature, velocity and pressure gradient expressions. A polynomial solution technique is utilized to obtain these mathematical solutions. Finally, these computational results are presented graphically and different characteristics of peristaltic flow phenomenon are examined in detail through these graphs. The velocity declines as the volume fraction of carbon nanotubes increases in the base fluid. Since the velocity of fluid is dependent on its temperature in this study case and temperature decreases with increasing volumetric fraction of carbon nanotubes. Thus velocity also declines for increasing volumetric fraction of nanoparticles.
