Residence time distribution [PDF]
, 1984 Slurry phase residence time in the SRC-II dissolver is a major process variable affecting the extent of conversion to distillate products. Kinetic studies have shown that overall conversion of vacuum bottoms to lighter hydrocarbons is a zero order process with respect to vacuum bottoms.

Residence Time Distribution of an Irregular Octagonal Tank under Hydrodynamic Sloshing Effect
Chemical Engineering Transactions, 2023 Sloshing is the movement of fluid in a partly filled vessel subjected to external motions. Generally, sloshing is an undesirable motion for the purpose of marine operations as it causes intense forces and instability.

Interplay of Particle Suspension and Residence Time Distribution in a Taylor–Couette Crystallizer
Crystals, 2022 In small-scale continuous crystallization, particle suspension and residence time distribution are critical factors determining operability and product quality. Here, the Taylor–Couette crystallizer stands out for its high flexibility. Its characteristic

Introduction of novel characteristic time quantities to describe chemical reactors
Chemical Engineering Journal Advances, 2023 The Mean Residence Time is a quantity which is used very often to characterise chemical reactors. This quantity can be calculated using the Residence Time Distribution of a specific, continuous reactor and assuming closed-closed boundary conditions. Many

Effect of microchannel aspect ratio on residence time distributions and the axial dispersion coefficient [PDF]
, 2009 The effect of microchannel aspect ratio (channel depth/channel width) on residence time distributions and the axial dispersion coefficient have been investigated for Newtonian and shear thinning non-Newtonian flow using computational fluid dynamics.
