An Investigation on the Calculating for Optimal Lift of the Ring Valve
نویسنده
چکیده
This paper analyses the loss of energy in ring valves of the compressor, investigates the calculating method for the main structure parameter--optimal lift 0 and derives the calculating formula. The measument result on the ccmpressor L2-10/8-I shows that the valves designed through this calculating formula has more tangible result for economizing energy than others.

The Effect of Valve Lift on In-Cylinder Flow, Performance and Emissions in a Turbocharged DI Diesel Engine
A computational optimization was performed for a direct-injection diesel engine using three-dimensional modeling. Fully transient CFD analyses of different valve profile strategies for the intake and compression strokes were performed to evaluate the effects on both engine performance and in-cylinder flow-field evolution. The turbulence model was used along with the second order linear upwin...
متن کاملDeveloping a Novel Temperature Model in Gas Lifted Wells to Enhance the Gas Lift Design
In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. Also g...
متن کاملNew Method of Determination for Pressure and Shear Frictions in the Ring Rolling Process as Analytical Function
Ring rolling is one of the most significant methods for producing rings with highly precise dimensions and superior qualities such as high strength uniformity, all accomplished without wasting any materials. In this article, we have achieved analytical formulas for calculating the pressure and shear friction over the contact arcs between the rollers and ring in the ring rolling process for the ...
متن کاملCalculating Magnetic Permeability Response of a Conducting Square Ring Structure
In the present work, we investigate the tunability of the magnetic response of a new structure. A lattice of periodically arranged close-packed square conducting rings has been studied for this purpose. Here, instead of enhancing the magnetic activity via resonance, like in split-ring resonators, we concentrate on the analysis of the interactions between these rings. The core idea is to design ...
متن کاملNumerical investigation of the effect of swirl and needle lift profile change on the diesel fuel spray behavior
In this study, the effect of creation swirly flow and needle lift profile change on the behavior of the diesel fuel spray considered. To this end, two phase flow inside the diesel injector was simulated using the CFD. Solid works software has been used for geometry creation and AVL-Fire software has been used for meshing and simulating. Firstly, the liquid flow and spray characteristics of the ...
