the aim of this study was to determine time dependent effects of high intensity interval training (hiit) on oxygen kinetics in young males. 40 active students were randomly assigned to four groups: one session of hiit, two sessions of hiit, four sessions of hiit and control. both hiit and control groups performed the incremental test on an ergometer bicycle. two days after the pretest, training...

Background. Because VO2max doesn’t provide any detailed information about aerobic examinations Oxygen Kinetic is used for more accuracy. Long intensive and repetitive exercises with sufficient time lead to increase in aerobic parameters like kinetic absorption of oxygen. Objectives. The purpose of this study was to determine time dependent effects of short-time high intensity interval...

A three-dimensional (3D) Euler-Euler gas-liquid two-phase mathematical model was developed for simulating the local transient fluid flow in a gas-induced pulsating flow bubble column using computational fluid dynamic (CFD) method, with multiple size group (MUSIG) model implemented to predict the bubble size distribution. Model simulated results such as local transient axial liquid velocities an...

In this paper computational analysis of circulating fluidized bed combustion using the fluent software is analysed. This work is concerned about gas–solid two-phase mixtures flowing upwards through the fast beds. The procedures studied are applicable to all types of fluidized-bed boilers. The type of information resulting from various ways of analyzing the pressure and temperature in fluidized ...

[1] We present two depthand phase-resolving models, based on singleand two-phase approaches for suspended sediment transport under water waves. Both models are the extension of a wave hydrodynamic model Cornell Breaking Wave and Structure (COBRAS). In the two-phase approach, dilute two-phase mass and momentum equations are calculated along with a fluid turbulence closure based on balance equati...

Bubble plume models are applied to study the de-stratification of lake water, aeration of reservoirs, wastewater treatment, and gas injection into liquid metals. Several existing models exemplify numerical modeling as problem-specific art, solve a mixture momentum equation, and have limitations in the availability of documentation, definition of boundary conditions, and postand pre-processing c...
