Numerical modeling and optimization of pump behavior Ayrlyft

Ayrlyft pump device that is created by using levitation force accumulation of gas injected in a liquid column, capable of pumping liquid or solid particles desired in the liquid height is higher. In this article the effect of parameters such as effective diameter, float ratio, tube length and flow regime on the performance of a pump Ayrlyft, the form has been studied numerically. Also in the study area conditions and optimize the performance of pumps have been established. Comparing the results of numerical analysis with experimental results indicates the accuracy of this method is desirable. Results indicate that increased buoyancy and reduced diameter ratio improved performance is the pumps. It also increases the effect of pipe length on the performance of these pumps Bhszayy not.
