Abstract
In order to analyze gas flow, oxygen concentration and temperature fields of the gas and zeolite in a zeolite column at an adsorption-type oxygen concentrator, theoretical analysis was conducted. In this analysis, the equation of ideal gas, the Langmuir's equation, mass conservation equation of oxygen and nitrogen gas, energy conservation equation of gas and zeolite and the equation for gas velocity in the column were used. Spatial distributions of gas velocity, oxygen concentration, and gas temperature were analyzed numerically.
