In the present paper, an optimized design procedure capable of providing geometry a high efficiency compact hydraulic propeller turbine for low head is proposed and developed. The preliminary based on fundamental turbomachinery mean-line equations employment statistical correlations, which relate main geometrical parameters to parameters. first obtained represents starting point automated aerod...

An experimental investigation of centrifugal pump has been carried out to study its characteristics in and turbine mode operation (PAT). The correlation between PAT performance is a major problem. Several methods have developed predict the best efficiency pumps running as turbines, but their results are not good coincidence with data for all pumps. Fluid dynamic behavior changes appreciably, rel...

It is considered the mathematical model of a benchmark hydroelectric power plant containing water reservoir (lake), two conduits (the tunnel and turbine penstock), surge tank hydraulic turbine; all distributed (Darcy-Weisbach) local losses are neglected,the only energy dissipator remains throttling tank. Exponential stability would require asymptotic difference operator associated to model. How...

Hydraulic energy is one of the most important sources renewable today. It also a complementary source to other sources, being only that offers an nonpolluting storage capacity (through pump facilities). Another essential quality hydraulic its ability regulate system allow integration in which process generating depends on factors cannot be controlled (sun, wind, etc.). However, hydropower plant...

Present day jet engines are controlled and monitored by a series of hydraulic, fueldraulic, electrical and pneumatic sub-systems known as the Full Authority Digital Engine Controller (FADEC). At the heart of the FADEC lies a centralised Electronic Engine Controller (EEC) responsible for control and safety of the wider engine system. It has long been postulated that a distributed EEC would contr...

This paper is focused on the guide vane cascade as one of most crucial stationary sub-systems hydraulic turbine, which needs to provide efficient inflow conditions runner. The vanes direct flow from spiral casing and stay towards runner, regulating desired discharge. A parametric design tool with normalized geometrical constraints was created in MATLAB, suitable for generating geometries Franci...

This article presents the methods of specifying potentiality energy recovery in turbine installations projected to hydraulic regulation heating medium Krakow District Heating System. To achieve this, creating calculations enabling indicate best places install turbines System is necessary. For this reason, a great amount work - like choosing methodology and optimal calculation program, an actual...

Fish-like, dolphin-like, and bionic nonsmooth surfaces were employed in a hydraulic torque converter to achieve drag reduction and performance improvement, which were aimed at reducing profile loss, impacting loss and friction loss, respectively. YJSW335, a twin turbine torque converter, was bionically designed delicately. The biological characteristics consisted of fish-like blades in all four...
