| Abstract: | A new device for solution concentration, based on the coaxial two impinging-stream principle, was built and studied experimentally and theoretically. A reasonable mathematical model was developed according to theoretical analysis, which was proved correct by experimental verification. The behavior of air and droplets in the impinging stream concentrator (ISC) was numerically simulated. The trajectory of droplets and the variations of gas and droplets temperature, gas and droplets velocity, evaporated liquid rate in the ISC with axial distance were obtained. |
