Momentum transfer in turbulent pipe flows (d = 51 mm) with and without a drag reducer was studied. Age distributions of coherent fluid structures at the pipe wall were determined at different Reynolds numbers (10 4 < Re < 6 × 10 4 ) using laser-Dopp

An application-oriented design procedure is presented for completely mixed liquid reacting systems in batch reactors. These systems can safely be operated by neglecting the heat capacity of the vessel and attributing suitable values to three scale-in

A model is presented for gas-liquid flow and for the stratified-wavy-to-intermittent (slug or semislug) flow-pattern transition in slightly inclined pipes. The main parameter for predicting instabilities in stratified-wavy flow is the liquid hold-up,

An application-oriented design procedure is presented for unique and point-stable operations of first-order reaction systems in a continuous stirred-tank reactor (CSTR). For a given set of values of kinetic constants, reaction enthalpy, feed conditio

A model is presented for transient, cocurrent gas-liquid pipe flow in the stratified-smooth and stratified-wavy flow regimes. It is based on the equations of continuity and motion in the direction of flow and results in two hyperbolic partial differe

The present paper reports on the behaviour of a pseudo first-order reaction system in a batchwise operated stirred tank reactor. The experimental results refer to runaways, sensitive and stable operations and are compared with two different runaway c

A process-engineering model is presented for the stratified-wavy-to-intermittent (SW-I) flow-pattern transition in slightly inclined gas-liquid pipe flow. The main parameter for predicting (in)stability of wavy flow in inclined pipes is the average l

In a pulsed packed column (PPC) the mass transfer to solid cation-exchange particles is investigated during countercurrent flow of solids and a diluted aqueous hydroxide solution. It was found that pulsation of the liquid results in a better dispersi

In this paper, it is shown that the rate of hydrogen absorption into an aqueous solution is considerably enhanced by the presence of small particles, provided that (a) particle-to-bubble adhesion occurs, so that, during the absorption, a sufficiently

A model is presented for a quantitative prediction of the transfer coefficients of momentum, heat and mass, and the radial profiles of the axial velocity, the temperature, and the concentration in the near-wall fluid of a turbulent pipe flow. In this
