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.

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
