Thermal System Design and Optimization

Gastaldi, C. November 21, Gas Turbines Power. The purpose of this paper is to develop an attractive tool for designers in the initial design phase of the damping of turbomachinery blades through dry friction underplatform dampers. The paper shows how, to this purpose, certain reasonable simplifications are introduced in the procedure and in the model, leaving the customary full high fidelity computations to the final design verification analysis. The key simplifications here considered are: the blade neck is modelled with Euler beam finite elements FE to speed up the updating of its dimensions during the optimisation process; the contact forces exerted by the dampers on the blade platform are represented by the resultant forces and moments applied to a reference point on the platform, associated to its displacements and rotations; the airfoil, which, due to its complex shape, is considered fixed during the coupled optimization of the damper, is obtained from a full 3D FE model after a component mode synthesis reduction.

It is shown that the process captures the essentials of the nonlinear dynamics of the blade-damper problem without sacrificing in any way the accuracy of the results. This hybrid model is then employed in the process where the domains of optimal matching between the damper and the blade is searched for by exploring the influence of blade neck thickness flexibility and damper mass.

Such a purposely simplified process allows a clear identification of relationships between relevant blade features and response with a focus on fatigue life. Sign In or Create an Account. Sign In.

Which was going to be damned inconvenient. She knew exactly what she meant. Houses had taken on up to ten feet of water depending on where they were and how high the foundations were elevated. There were bricks knocked off retaining walls, fences down, roofs missing. Okay, so this whole talking thing had been a bad idea. His throat was dry and felt like it was caked with dirt.

Satellite system design is a process involving various branches of knowledge, in which the designer usually needs to tradeoff many essentials and takes remarkable time. While multidisciplinary design optimization MDO method provides an effective approach for complicated system design, it seems especially suitable for such kind design purpose. By applying MDO in satellite system design, the efficiency of design can be expected to be improved and powerful technical supports can be obtained, which means better performance, faster design process and lower cost. According to the Resource satellite mission, width of ground cover and ground resolution are taken as the performance measurement, which combined with total mass of satellite is accounted in the optimization objective in system level.

Приближающаяся медсестра прямо-таки кипела от возмущения. - Роса? - Беккер сжал руку Клушара. Старик застонал. - Он называл ее… - Речь его стала невнятной и едва слышной. Медсестра была уже совсем близко и что-то кричала Беккеру по-испански, но он ничего не слышал. Его глаза не отрывались от губ Клушара. Он еще раз сжал его руку, но тут наконец подбежала медсестра.

Почему же не открывается дверца. Вглядевшись, она как в тумане увидела еще одну панель с буквами алфавита от А до Z и тут же вспомнила, что нужно ввести шифр. Клубы дыма начали вытекать из треснувших оконных рам. Сьюзан в отчаянии колотила в дверную панель, но все было бесполезно. Шифр, подумала. Кабинет постепенно утопал в дыму. Стало трудно дышать.

Быстро пришлите сюда людей. Да, да, прямо. К тому же у нас вышел из строя генератор.

Чтобы развеять эти опасения, конгресс объявил, что, когда алгоритм будет создан, его передадут для ознакомления лучшим математикам мира, которые должны будут оценить его качество. Команда криптографов АНБ под руководством Стратмора без особого энтузиазма создала алгоритм, который окрестила Попрыгунчиком, и представила его в конгресс для одобрения. Зарубежные ученые-математики проверили Попрыгунчика и единодушно подтвердили его высокое качество. Они заявляли, что это сильный, чистый алгоритм, который может стать отличным стандартом шифрования. Но за три дня до голосования в конгрессе, который наверняка бы дал добро новому стандарту.
