Abstract
Orifice flow meter constitutes one of the most common differential pressure flow meters. However, high energy loss is occurred with the measurement process. The present research considers 3๐ท steady simulation using Reynolds Averaged Navier–Stokes equations (RANS). New design of the orifice plate s carried out using the adjoint method. Optimal shape of orifice plate shows 55 % reduction of the pressure loss coefficient at a Reynolds number ๐‘…๐‘’=1.84 × 104. The discharge coefficient ๐ถ๐‘‘ is increased by 39 %. Also, the effect of downstream ring is investigated. Optimize the shape of the ring has a slight effect on reducing energy consumed. However, applying adjoint method on the orifice plate with downstream ring achieves considerable effect in the pressure loss. Reduction by 34 % in pressure loss coefficient is obtained by the optimal orifice with downstream ring. Shape optimization by the adjoint method has a significant contribution in decreasing the consumed energy through the orifice meter.
