In the present study, a reduced model of Francis-99 turbine was investigated numerically at part load operating condition. The consists standalone draft tube domain turbine. Numerical studies performed in past on nearly complete hydro-turbine models (inclusive spiral casing, distributor domains, runner, and tube) reportedly consist large number computational grids. This may increase costs data ...
The ambivalence implicit in the two versions of Ridley Scott's Blade Runner (1982; "Director's Cut," 1992) echoes the diverse and divided critical responses to the film(s). Indeed, this film about authenticity and simulation has been so thoroughly interpreted and rewritten—by even its director—that a naive return to the "original" is, perhaps fittingly, untenable. This essay does not advance a ...
In order to discuss the surface pressure pulsation characteristics of magnetic-fluid sealing membrane centrifugal pump, this paper studies shaft end under different flow operating conditions pump based on combination numerical calculation and experimental verification. The results show that value film decreases with increase rate has periodic pulsation, period is time required for a single blad...
