Leakage Calculation Through Clearances

چکیده
Gas leakage tlow through small clearances is modeled using two-dimensional (2-D) and quasi one-dimensional {1-D) flow analysis. For 2-D approach, a dimensionless form of Navier-Stokes equations for two-dimensional, laminar, viscous and compressible fluids are employed to compute the det-·1iled tlow field across the clearance. The 2-D study also establishes that when clearance (0) is very small compared to tl1e lengili (L), i.e., OIL nee Geometry_ clearances of scroll compressors. 2-D APPROACH Two-dimensional Navier-Stokes equations were used to calculate the flow field. The flow was assumed to be compressible, viscous nnd laminar. Ideal gas law was employed for equation of state. The system of partial differential equations governing this type of flow is described as follows in non-dimensional fonn for Cartesian coordinate:

Modeling and Experimental Investigation on the Internal Leakage in a CO2 Rotary Vane Expander
A rotary vane expander has been developed to replace the throttling valve for improving the COP of transcritical CO2 refrigeration system. Due to the serious internal leakage, the expander efficiency is not satisfactory. This paper presents the theoretical and experimental investigation on the internal leakage in a rotary vane expander prototype. Firstly, the leakage flow rate through the inter...
متن کاملEffect of a ring type barrier and rotational speed on leakage flow of gas turbine brush seal
This paper investigates the effect of inserting a ring type barrier on leakage flow of brush seals with different bristles clearances (the distance between bristle pack tip and rotor surface). The ring is placed on both upstream and downstream sides of the bristles. An axisymmetric CFD model is employed to calculate radial pressure distribution along backing plate, axial pressure variation on r...
متن کاملResearch of Oil-Injected Scroll Compressor Working Process
The working process of oil-injected scroll compressor is analysed in this paper. The thermodynamic and dynamic models arc developed for the oil-injected scroll compressor. The property parameters can be calculated under the influences of the leakage and the friction. The results of computer simulation are coincident with the experiment's. so it is useful to predict the compressor performance. I...
متن کاملUrea Excretion at Low Urine Volumes. the Calculation of "minimal" Urea Clearances.
In a previous paper (1), it was shown that the calculation of standard urea clearances from urine volumes of less than about 0.35 ml. per minute gives results which are considerably too low. It was found that the lower the urine volume is, the greater the error becomes, as the calculated standard clearance falls lower and lower. This was demonstrated in 173 adults, including patients with toxem...
متن کاملCalculation of Leakage in Water Supply Network Based on Blind Source Separation Theory
The economic and environmental losses due to serious leakage in the urban water supply network have increased the effort to control the water leakage. However, current methods for leakage estimation are inaccurate leading to the development of ineffective leakage controls. Therefore, this study proposes a method based on the blind source separation theory (BSS) to calculate the leakage of water...
