    Abstract: So-called wall flows are usable in many technical applications as a simple and reliable device for exhausting of light materials as dust, smoke, hot air, etc. In another cases, such flows can make troubles by treatment of light materials as fibers, etc. and it is necessary to suppress the wall effects by suitable design adjustments. But there is de... Show More

    This article belongs to the Special Issue Numerical Flow Simulations in Textile Industry
    Abstract: The contribution describes frequent functional problems of exhausting devices, caused by no observing of essential rules of fluid mechanics. For instance, due to the unbalanced tubing system of several branches the medium flows in individual connections and their relevant energy transports are not corresponding to the designed one, or the diffuser ...
