چکیده

Analytical solutions are obtained for both the radius-time relation and the rate of solution by diffusion of a gas bubble in plasma and whole blood with reduced hemoglobin. If an oxygen bubble is situated in the blood. a concentration boundary is formed in which the combined processes of diffusion and chemical reaction takes place. The effect of surface tension on the bubble dynamics is also considered. Applications of the analytical results include the extracorporeal oxygenation of the blood and the determination of the diffusion coefficient in plasma and the reaction velocity constant in whole blood.

Gas bubbles of oxygen. carbon dioxide and nitrogen are injected into the degassed plasma and whole blood. The bubble size is measured at time intervals until the bubble is completely dissolved in the liquid. Physical quantities governing the dissolution of gas bubbles are identified and their effects are examined. The applications of the study include the dissolution of gas emboli in human body...

CFD-DEM Investigation on van der Waals Force in Gas-Solid Bubbling Fluidized Beds

Effect of interparticle force on the hydrodynamics of gas-solid fluidized beds was investigated using the combined method of computational fluid dynamics and discrete element method (CFD-DEM). The cohesive force between particles was considered to follow the van der Waals equation form. The model was validated by experimental results from literature in terms of bed voidage distribution and Eule...

Experimental studies of the dissolution of gas bubbles in whole blood and plasma. II. Moving bubbles or liquids.

Paxt 1 of the study is concerned with the dissolution of a gas bubble in quiescent. degassed blood and plasma. This paper is an extension of the experimental study to include the case in which the gas bubble dissolves in degassed blood and plasma impinging upon it. Results are compared with those of part I and the effects of relative motion between the bubble and the liquid are examined. It is ...

Plasmas sustained in bubbles in water: optical emission and excitation mechanisms

Plasmas in bubbles in water are being investigated for their ability to produce chemically reactive species for water purification and medical treatment. The gas forming the bubble is potentially a design parameter for water purification as the type and rate of production of active species may be controllable by the type of gas in the bubble. In this paper, we report on a computational investig...
