. The model showed an excellent thermal-hydraulic performance compared to other conventional channel shapes of the PCHE including straight, zigzag, wavy etc., showing above 90 % pressure drop decrease for the similar thermal performance. However, the optimal performance of the PCHE design has not been well
IMECE2002-34030 OPTIMAL DESIGN OF A SMART CONFORMABLE ROTOR AIRFOIL
"... ABSTRACT An optimization method has been developed for the design of a smart conformable rotor airfoil with distributed piezoelectric actuators. A conformable airfoil is proposed as a substitute for trailing edge flaps used for helicopter vibration reduction by achieving high frequency camber varia ..."

Aerodynamic and Aeroacoustic Optimization of Airfoils via a Parallel Genetic Algorithm
- In Proceedings of the 7th AIAI/USAF/NASA/ISSMO Symposium on Multidisciplinary Analysis and Optimization
, 1998
"... A parallel genetic algorithm (GA) was used to generate, in a single run, a family of aerodynamically efficient, low-noise rotor blade designs representing the Pareto optimal set. The n-branch tournament, uniform crossover genetic algorithm operates on twenty design variables, which constitute the co ..."

an overall noise measure including effects of loading and thickness noise of the airfoil. Constraints are placed on minimum lift coefficient, pitching moment and boundary layer convergence. The program XFOIL provides the aerodynamic analysis, and the code WOPWOP provides the aeroacoustic analysis. The Pareto-optimal
Shear Morphing Skins Simulation and Testing of Optimized Design
"... ABSTRACT: Previous work designed and tested novel morphing wing designs that were enabled by ‘shear-morphing ’ skins capable of withstanding 400 psf (19.15 kPa) airloads while simultaneously undergoing shear strains over 100%. These ad hoc skin designs consisted of high-strain silicone facesheets su ..."

. In this research, with the use of high-fidelity modeling (ANSYS) and in-house testing, a new design was obtained that met both of the desired objectives using novel materials and single-piece support structure fabrication. Using an optimized design from analysis, the ANSYS code was validated through manufac
1 Impact of Airfoils on Aerodynamic Optimization of Heavy Lift Rotorcraft
"... Rotor airfoils were developed for two large tiltrotor designs, the Large Civil Tilt Rotor (LCTR) and the Military Heavy Tilt Rotor (MHTR). The LCTR was the most promising of several rotorcraft concepts produced by the NASA Heavy Lift Rotorcraft Systems Investigation. It was designed to carry 120 pas ..."
