Viscosity influence on hydrodynamics behaviour in a stirred tank reactor

Popis výsledku v původním jazyce

Mass transfer-based processes are gaining prominence in the chemical and biochemical industries. One critical unit for mass transfer is the gas-liquid contactor, which can be agitated mechanically or pneumatically. The design and optimization of these devices are governed by key parameters, including gas hold-up, power input, and the volumetric mass transfer coefficient. These parameters are influenced, in part, by the physical properties of the system, such as liquid viscosity. The primary objective is to investigate how gas hold-up and power input are affected by changes in viscosity, while elucidating the associated trends through the behavior of gas bubbles (gas-liquid interfacial area and mass transfer coefficient). Measurements of total gas hold-up and power input were conducted under varying operational (gas flow rate, impeller speed), geometrical (impeller types), and chemical (batch type) conditions, with viscosity systematically varied across a broad range. Given the extensive array of variables, the observed trends in relation to viscosity can be considered as characteristic properties of liquid behavior.
