The proposed work will test the feasibility of using a relatively new three-equation turbulence model to achieve accurate predictions of nonequilibrium turbulence in flows related to high-lift syste ...

Nielsen Engineering & Research (NEAR) proposes to employ its updated flexible fin and fin planform optimization technologies to control/minimize missile fin hinge moments while maintaining normal fo ...

Nielsen Engineering & Research (NEAR) proposes to develop a new missile control fin design method to maximize fin normal force, minimize actuator requirements, and control fin wake. Current design ...

The goal of the work is to develop a physics-based method for predicting clear air turbulence (CAT). Two levels of prediction will be employed: direct simulation of the intermediate scales of motion ...
