Design and simulation of gas mixing valve

This study presents a design methodology for a mixing valve for two gases. The first of the gases have an ultra-low pressure and velocity, while the second have a fastest mobility. Taking advantage of the Bernoulli effect, a Venturi-type mixer is implemented to take advantage of the fast speed primary gas to create a slightly suction to move the secondary gas. To validate this methodology, simulation results of the designed valve are shown. According to the results, the suction present in the low pressure line is enough to dislodge the secondary gas without cause vacuum.
