Prediction Approach

Laminar flow control (LFC) is one of the key enabling technologies for quiet and efficient supersonic aircraft. Recent work at Arizona State University (ASU) has led to a novel concept for passive LFC, which employs distributed leading edge roughness to limit the growth of naturally dominant crossflow instabilities in a swept-wing boundary layer. Predicated on nonlinear modification of the mean boundary-layer flow via controlled receptivity, the ASU concept requires a holistic prediction approach that accounts for all major stages within transition in an integrated manner. As a first step in developing an engineering methodology for the design and optimization of roughness-based supersonic LFC, this paper reports on canonical findings related to receptivity plus linear and nonlinear development of stationary crossflow instabilities on a Mach 2.4, 73° swept airfoil with a chord Reynolds number of 16.3 million.

Screen Print

Silk-Screen Print Technique was used to print roughness elements at the leading edge of a swept wing for crossflow (CF) dominated Laminar Flow control (LFC) in fluid dynamics. Crossflow was studied to be sensitive to the spacing and height of the roughness elements, as well as the density of the metal ink. Experiments in our research showed silk-screen print technique can precisely print the elements to dominate to delay transition.
