Abstract:

Mass injection upstream of the tip of a high-speed axial compressor rotor is a stability enhancement approach known to be effective in suppressing stall in tip-critical rotors. This process is examined in a transonic axial compressor rotor through experiments and time-averaged Navier-Stokes CFD simulations. Measurements and simulations for discrete injection are presented for a range of injection rates and distributions of injectors around the annulus. The simulations indicate that tip injection increases stability by unloading the rotor tip and that increasing injection velocity improves the

Abstract:

A new approach, steady micro air injection from the casing, is proposed to improve the stability of a three-stage low-speed axial compression system. Although the injection rate is designated to be only a few ten thousandth of the compressor flow rate, such an injection is able to trigger the unsteady response and thus lower the mass flow rate at stall for up to 5.83%. At the same time, it keeps the steady compressor characteristic with no injection unchanged. In order to verify that the compressor response is indeed unsteady, experiments at various injection configurations are performed, whic

Abstract:

Through the discussion of main shortages of the high-speed electromagnetic valve used in electronic fuel injection system, the author introduced a new design thought of fuel injector based on 2D technology. Axial displacement of controlling valve was used to control the volume of gushing oil, while radial revolution of spool valve was used to change the time of injection. Additionally, mathematic modeling and MATLAB simulating indicated that, the injector designed based on 2D technology acquired the advantages of quick response and also realized the ideal shape of fuel injection rate.

Abstract:

The most common technique used for non-surgical treatment of trigger fingers is the direct injection of steroids into the flexor tendon sheath over the metacarpal head. However, this method causes more pian to the patient and can result in tendon rupture due to insertion of needle into the tendon. Carlson and Curtis described the mid-axial injection technique which is simple and relatively painless. We aim to compare the pain result from the injection between these two methods. The prospective randomised control trial study was designed. There were 103 trigger fingers included in the study whi

Dorsal injections of XHNF1(beta)/EngR mRNA abolish dorsal mesoderm formation, leading to axial deficiencies; ventral injections disrupt ventral mesoderm formation without affecting axial development.

Analyzed the force of the separated zone water injection string, and established the physical model and mathematical model. Using the traditional boundary processing method of tubular mechanics to calculate the displacement of separated zone water injection string, discovered that the accuracy cannot meet the requirement of the oilfield. Therefore consider the influence of all packer’s frictional force on the water injection string’s stress condition, and propose a new method to deal with the bou

Abstract:

This paper presents the use of pulsed air injection to control rotating stall in a low-speed, axial flow compressor. In the first part of the paper, the injection of air is modeled as an unsteady shift of the compressor characteristic, and incorporated into a low dimensional model of the compressor. By observing the change in the bifurcation behavior of this model subject to nonlinear feedback, the viability of various air injection orientations is established. An orientation consistent with this analysis is then used for feedback control. By measuring the unsteady pressures near the rotor fac

Abstract:

Background: The injection of mixture of plain bupivacaine and triamcinolone acetonide into the sacroiliac joint (SIJ) to relieve chronic low back pain is uncommon in the West African sub-region. The objective of this study was to demonstrate the efficacy or otherwise of fluoroscopic-guided SI joint injection in the management of chronic axial low back pain in Nigeria.Design: This was a prospective observational interventional studySetting: The study was carried out at a tertiary hospital in NigeriaParticipants: Twenty-six patients with SI joint pain, based on IASP diagnostic criteria, who pres
