To study instability in the unsteady cavitating flow a liquid rocket engine inducer, visualization experiments of non-cavitating and flows inside model inducer were carried out at different conditions. Visual to capture evolution three-bladed by using high-speed camera. The external characteristic performance, cavitation pressure pulsation analyzed based on observation non-cavitation developmen...

Background: Bone marrow stromal cells (BMSC) are used as a source for cell therapy in different model for neurological disorder such as stroke and spinal cord injury. However, the transdifferentiation of BMSC into cholinergic phenotype requires more investigation. Methods: BMSC were isolated from adult rats, pre-induced with β-mercaptoethanol (BME) and followed by nerve growth factor (NGF) indu...

The influence mechanism of the blade tip clearance (TC) an inducer on performance a centrifugal pump at high speed was researched under different flow rate conditions in this work. An experiment pump’s external carried out, and numerical calculation also performed four TCs. full characteristic curves, static pressure pulsation distributions were obtained. Through research analysis, it found tha...

one of the most problems that limits use of turbomachines at high speed applications is cavitation. cavitation can damage casing and blades of turbopump, also can make unstability in system. inducer that was installed in front of main impeller can improve cavitation characteristic of system and increase static pressure just before entrance of centrifugal pump. specially in fuel feed system of l...

Inducer is often used to improve the cavitation performance of pump. In order study characteristics inducer under low flow condition high-speed pump, photography technology was employed in this paper carry out visual experiments on a centrifugal rates, Cavitation distribution and evolution among were captured. The experimental results revealed that band-shaped backflow vortex inlet pipe would o...

In this work, we propose the finite-element-based mathematical model of metal-inducer system. This system consists a coil with put-on C-shaped ferromagnets. We study how measurands inducer, such as voltage and uncompensated force acting on metal, depend parameters. variate geometry to estimate boundary effect impact. Also, depends ferromagnets' spacing their number. The inhomogeneity electric c...
