“…Only a few studies provide downstream noise spectra generated by cavitating orifices (Yan et al, 1988;Bistafa et al, 1989;Kim et al, 1997;Pan et al, 2001). A few complementary studies give the noise spectra created by cavitating valves (Hassis, 1999;Martin et al, 1981).…”

“…Orifice plates with small diameter ratios were tested to determine the effect of plate thickness and cavitation on orifice meter discharge coefficient experimented by B.-C. Kim et al [8]. The inception of cavitation as measured by the following three methods was in agreement: 1. an increase in the spectrum from a hydrophone downstream of the orifice meter 2.…”

Orifice metre in simplest form is a hole in plate which is introduce in flow to determine discharge of flow. The orifice metre is the cheapest and simplest method to carryout flow analysis. However, this process has major drawback of energy transmutation phenomenon; which is accompanied by various losses. In order to wrest these drawbacks; instead of single hole Multi-hole orifice is preferred. The paper aims on review of several annals in the field of flow measuring techniques aided by Multi-hole orifice plate. The paper elaborates analysis of various flow parameters associated with Multi-hole orifice plate and their physical existence in the flow; also, how this method is efficient than conventional method. Various analysis method such as CFD, finite elemental methods, numerical methods and experimental methods are elaborated in this paper suggesting efficient functioning of Multi-hole orifice plate. The future prospects in the respective field through exploration of the developments in its applications and research this far are also discussed.

“…Many researchers investigated experimentally the cavitation characteristics of different devices; among them, Tullis, 2,7 Kim et al, 8 Testud et al, 9 Maynes et al, 10 and Malavasi et al 11 focused on single-and multi-hole orifices. However, the already mentioned procedure reported in the ISA-RP75.23-1995 1 and IEC 60534-8-2 6 for estimating the incipient cavitation index by means of SPL or pipe wall acceleration measurements is not free from difficulties mainly arising from the fact that the change in slope in the plot of Figure 2 is not always clearly identifiable, even in the presence of a large number of sampling points.…”

Due to its serious consequences, cavitation in pipeline systems is one of the main concerns of engineers. In this context, the incipient cavitation index defined in many international standards such as those from International Society of Automation and International Electrotechnical Commission is a very important parameter as it accounts for the onset of cavitation. However, the standards define only the experimental determination of the incipient cavitation index, which is furthermore difficult to perform due to the considerable technical and economical burden of the experimental tests, above all in case of large-size systems. In this work, we propose a new method for predicting the incipient cavitation index by means of computational fluid dynamics, avoiding the need of making any experiment. The method is based on the generalized pressure criterion and requires only one Reynolds-averaged Navier–Stokes simulation of single-phase incompressible flow to provide estimates of the incipient cavitation index. The method is applied to predict the incipient cavitation index of multi-hole orifices with different geometrical characteristics, in terms of equivalent diameter ratio (0.40–0.70), relative thickness (0.73, 1.00), and number (13–52) and disposition of the holes. The experimental data revealed the reliability of the method. Its applicability was also confirmed for more complex geometries, and an application example regarding a control valve is briefly illustrated at the end of this article
