Power Input of High-Speed Rotary Impellers
Acta Polytechnica, 2001 This paper presents the results of an experimental investigation of the power input of pitched blade impellers and standard Rushton turbine impellers in a cylindrical vessel provided with four radial baffles at its wall under a turbulent regime of flow ...

International Journal of Chemical Engineering, 2018 In recent years, a novel home base-type (HB-type) impeller was developed to be based on observation of the streak line pattern. An HB impeller must be simple, speedy, and stable (3S). When an HB impeller is used on the laboratory beaker scale, the mixing

Observations on Instabilities of Cavitating Inducers [PDF]
, 1978 Hydraulic systems involving cavitating turbomachines are known to be susceptible to instabilities at certain critical operating conditions. Two distinct classes of cavitating inducer instabilities have been reported in the literature (Refs. 1-6).

Dynamic pH profiles drive higher cell‐specific and volumetric productivity
Biotechnology Progress, EarlyView.Implementation of dyamic pH profiles for increased CHO cell culture productivity. Abstract Mammalian cell cultures in bioreactors rely heavily on critical process parameter control to ensure optimal growth, productivity, and reproducibility to produce recombinant therapeutic proteins. Culture pH has been shown to be a critical parameter that influences

Journal of Consumer Behaviour, Volume 24, Issue 2, Page 632-654, March 2025.ABSTRACT Existing research examines the relationship between personal life shocks and financial well‐being primarily through the lens of objective markers of the individual's financial situation (e.g., liquidity). Little attention has been paid to the relative roles of these objective markers and more intuitive or affect‐based factors in how an ...
