Design of air nozzle for air curtains

The procedure, which is used in the design of air nozzle intended to be on curtain, described this work. present work focused isolated flow one nozzle, while next will continue with nozzles constellation. Nozzle reach field monitored and without tangential simulating non-isothermal flow. Several basic shapes same cross-section are evaluated. After searching space parametric CAD model simulated isothermal – flow, best configuration longest range were selected. From smaller set was selected highest directional stability field. shape minimal deviation subsequently optimized by adjoint method. This method makes it possible further reduce pressure loss distribution element deforming according local sensitivity cost function deformation. final step process verify effect modified both filed.
