“…Results obtained showed improvements in valve performance with one or two trims. The number of trims has to be restricted purely on cost factor especially, when the trims are more than three [7]. In [8], "cavitation occurs when the local pressure drops below the saturation pressure.…”

The importance of globe valve in fluid handling and control cannot be overemphasized. It is useful in oil and gas applications. If globe valve is not properly modelled, its primary purpose of regulation of fluid flow may be defeated. In this work, model of globe valve is developed from basic mechanical principles. The resulting model is a second order system whose response to a step input signal gives no overshoot. Further stability analysis with bode plot, Nyquist plot and root locus plot give a stable system indicating that the developed globe valve model is suitable for relevant areas of application.

“…The useful life of industrial valves and pumps are highly affected by the phenomenon of bubble collapse [21,22]. In [23], the authors investigate the effect of the number of trims on the performance of the globe valve and how it suppresses the cavitation problem. It should be mentioned that most of the proposed methods are not economically justified and demand to change the mechanical structure of valves and pumps.…”

The existence of a bubble in the vicinity of an elastic boundary appears in many situations such as medical and mechanical systems. On the other hand, bubble collapse is considered a source of energy loss in most systems and caused a lot of damages to it. This research is the first attempt to prevent bubble collapse in the vicinity of an elastic boundary by using control algorithms. In this paper, first, the nonlinear dynamic model of bubble in the vicinity of an elastic wall is introduced and then rewritten into state-space form. The second part of this paper is devoted to the design of the sliding mode controller for the bubble system, where the ultrasonic pressure plays the role of control input and the output is the bubble radius. Our main objective is to design a stabilizing controller that is able to regulate the radius of the bubble to the desired radius. At first, traditional sliding mode controller is proposed. Despite the successful tracking error, the chattering problem of this method leads us to introduce the boundary layer sliding mode control. Although the chattering phenomenon has been attenuated, it increases the steady-state error. Finally, robust integral sliding mode control is suggested to minimize the steady-state error while the chattering problem is removed. Numerical simulations including the case of parametric uncertainty are also presented. The results of this study are of immediate interest for medical applications such as ultrasound imaging and also industrial applications such as designing long-lasting pumps and valves.

“…Shaaban (2015) presented a perforated plate with optimized orifice structure, and an obvious delay of the cavitation onset was observed for the optimized plate. Yaghoubi et al (2018) found that the addition of one stage or two stages of perforated cylindrical plates reduces the intensity and delays the cavitation onset in the valve. Tang et al (2019) proposed an optimization method based on genetic algorithm, 3D geometric model simulation, and the topology optimization algorithm to control cavitation.…”

Perforated plates are prevalently used in various integrated energy systems for flow restriction, vibration, and noise reduction. The characteristics of flow energy transfer and loss in perforated plates have a significant impact on its piping systems. The existing design and previous studies largely paid little attention to the characteristics of flow energy variation, resulting in severe performance issues and energy consumption. In this study, the characteristics of energy transfer and loss of cavitation flow with various pressure ratios in single and multi-stage perforated plates were numerically studied. The parameters of energy ratio and energy gradient were developed to effectively evaluate the degree and rate of flow energy variation. Results showed that the contribution to energy loss generated from orifice outlet was relatively larger than the inlet and that the degree and rate of energy variation deceased with the increasing stages during the flow in multi-stage models. Additionally, increased stages of perforated plate resulted in a multi-stage stepped energy drop in throttling orifices, and lead to obvious suppression of the cavitation. This work intends to provide references to cavitation control and energy consumption optimization in piping systems using a perforated plate.
