Optimal design for disc golf by computational fluid dynamics and machine learning

چکیده

In this article, we introduce a computational methodology for golf disc shape optimization that employs novel parameterization by cubic B-splines. Through application of batch Computational Fluid Dynamics simulations and Machine Learning, the yields functional relationships—so-called surrogate models—between flying rotating its flight characteristics. The models facilitate free constrained in both single- multiobjective settings, such aerodynamic (drag lift) structural (mass moment inertia) features are addressed simultaneously. Further, Professional Disc Golf Association rules permissible discs can be cast as nonlinear constraints problem. proposed numerical method drag coefficient values low 0.48 (unconstrained) 0.52 (constrained) lift high 0.26 0.19 (constrained). presented results also describe many design tradeoffs between target long range (so-called drivers) at speeds putters). Moreover, optimal rule compliant designs driver-type putter-type discs, well their compromise, so-called mid-range discs.

Hydrodynamic Improvement of underwater glider by Computational Fluid Dynamics method

Gliders are new marine vehicles which have research and military uses and they move by sequent diving and climbing. Suitable design of its main body and wings are important for the most advance velocity. hydrodynamic design variables are main body form, wings (cross section, dimensions, shape, longitudinal and vertical position) and hydrostatic parameters (static trim angle, amount of added for...

Computational fluid dynamics for turbomachinery design

Computational fluid dynamics (CFD) probably plays a greater part in the aerodynamic design of turbomachinery than it does in any other engineering application. For many years the design of a modern turbine or compressor has been unthinkable without the help of CFD and this dependence has increased as more of the flow becomes amenable to numerical prediction. The benefits of CFD range from short...

Design optimization of blood shearing instrument by computational fluid dynamics.

Rational design of blood-wetted devices requires a careful consideration of shear-induced trauma and activation of blood elements. Critical levels of shear exposure may be established in vitro through the use of devices specifically designed to prescribe both the magnitude and duration of shear exposure. However, it is exceptionally difficult to create a homogeneous shear-exposure history by co...
