A method aimed at the development of an America’s Cup racing yacht bulb is developed and validated against experimental data.
The method relies heavily on Reynolds Averaged Navier Stokes computational fluid dynamics (CFD) and also factors in gravitational
and aerodynamics effects through the use of a Velocity Prediction Program. Initial extensive use of towing tank results is
made to be able to validate the CFD solution and thus develop a solid ground for predictive work. Then, in order to narrow
down the focus on bulb developments, decoupled hypotheses are made on the influence of the hull and free surface wave. The
development of a detailed performance analysis chart of a known base bulb allows the use of a relatively small series of CFD
simulations together with physical hypotheses to assess any given bulb performance relative to the known base. The discussion
of the results on a specific development highlights the promises and limitations of the method; final full scale results are
discussed and analysed as well. 相似文献

顶技术处理百合，不仅使鳞茎周径增大、鲜重明显增加，而且顶以后植株地上茎增粗，叶片变大变厚．实验结果表明，百合植株从显现花蕾至花蕾5cm长这段时间顶对增加百合鳞茎的大小和重量效果好，过早或过迟顶效果均不佳． 相似文献
