Estimation of mean water vapour residence time during tropical cyclones using a Lagrangian approach

Tropical Cyclone Research and Review, 2022
Tropical cyclone (TC)-related rainfall mostly depends on the atmospheric moisture uptake from local and remote sources. In this study, the mean water vapour residence time (MWVRT) was computed for precipitation related to TCs in each basin and on a ...

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

Evaluation of flow characteristics in an onshore horizontal separator using computational fluid dynamics

Journal of Ocean Engineering and Science, 2020
In the petrochemical industry, separation of oil from water is a very important process. Wells produce mixtures of gas, oil, and water which undergo a primary stage of separation inside horizontal gravity separators.

Subject-specific factors affecting particle residence time distribution of left atrial appendage in atrial fibrillation: A computational model-based study

Frontiers in Cardiovascular Medicine, 2023
BackgroundAtrial fibrillation (AF) is a prevalent arrhythmia, that causes thrombus formation, ordinarily in the left atrial appendage (LAA). The conventional metric of stroke risk stratification, CHA2DS2-VASc score, does not account for LAA morphology or

Soil Properties Control Microbial Carbon Assimilation and Its Mean Residence Time

Frontiers in Environmental Science, 2020
Microbial assimilation and stabilization of soil organic carbon (SOC) is an important process in global carbon cycling. For an improved understanding of climate-induced changes in ecosystem C dynamics, it is important to know the group-specific turnover ...

Interactive effects of catchment mean water residence time and agricultural area on water physico-chemical variables and GHG saturations in headwater streams

Frontiers in Water, 2023
Greenhouse gas emissions from headwater streams are linked to multiple sources influenced by terrestrial land use and hydrology, yet partitioning these sources at catchment scales remains highly unexplored.

Subject-Specific Calculation of Left Atrial Appendage Blood-Borne Particle Residence Time Distribution in Atrial Fibrillation

Frontiers in Physiology, 2021
Atrial fibrillation (AF) is the most common arrhythmia that leads to thrombus formation, mostly in the left atrial appendage (LAA). The current standard of stratifying stroke risk, based on the CHA2DS2-VASc score, does not consider LAA morphology, and ...

Submarine Groundwater Discharge From Sediments and Sand Boils Quantified by the Mean Residence Time of a Tracer Injection

Frontiers in Earth Science, 2021
To quantify submarine groundwater discharge, we developed an inexpensive automated seepage meter that applies a tracer injection and the computation of the mean residence time. The SGD-MRT is designed to measure a wide range of discharge rates from about
