RISConstrained Adjoint Based Aerodynamic Shape Optimization of a Single Stage Transonic Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops a discrete adjoint formulation for the constrained aerodynamic shape optimization in a multistage turbomachinery environment. The adjoint approach for viscous internal flow problems and the corresponding ...
Optimum Shape Design for Multirow Turbomachinery Configurations Using a Discrete Adjoint Approach and an Efficient Radial Basis Function Deformation Scheme for Complex Multiblock Grids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a framework for fully automatic gradientbased constrained aerodynamic shape optimization in a multirow turbomachinery environment. The concept of adjointbased gradient calculation is discussed and the ...
Development and Application of an Anisotropic Two-Equation Model for Flows With Swirl and Curvature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An anisotropic two-equation model is developed through a novel technique that involves the representation of the energy spectrum and invariance based scaling. In this approach the effect of ...

Abstract: The United States Department of Energy’s Pacific Northwest National Laboratory is teaming with industry to deploy and independently monitor 5kilowattelectric (kWe) combined heat and power (CHP) fuel cell systems (FCSs) ...
Semiempirical Method for Estimation of Pullout Capacity of Grouted Soil Nails in Saturated and Unsaturated Soil Environments
Publisher: American Society of Civil Engineers
Abstract: The design of soil nail systems used in engineering practice is either based on conventional soil mechanics or empirical procedures, and generally ignores the influence of matric suction. An experimental program was conducted ...
