This paper describes the simulation approach for the analysis of fluid structure interactions FSI of rocket thrust chambers. It is based on a partitioned approach and includes several buildingblocks: codes for computational fluid dynamics CFD and computational structural mechanics CSM as well as techniques to handle non conforming surface grid and to solve the nonlinear coupledequations in time. One target application is the life time prediction and to simulate the structuralfatigue behaviour. Thus, cyclic loading conditions are important and are the motivation for a surrogatemodel, which is the focus of this contribution.

This paper describes the simulation approach for the analysis of fluid structure interactions FSI of rocket thrust chambers.

It is based on a partitioned approach and includes several buildingblocks: codes for computational fluid dynamics CFD and computational structural mechanics CSM as well as techniques to handle non conforming surface grid and to solve the nonlinear coupledequations in time.

One target application is the life time prediction and to simulate the structuralfatigue behaviour. Thus, cyclic loading conditions are important and are the motivation for a surrogatemodel, which is the focus of this contribution. It uses nonlinear mapping algorithms between surfacetemperature and heat flux in combination with a reduction of dimensionality via proper orthognal decomposition POD.

It can be used as a replacement of the time consuming CFD code and acceleratesthe FSI analysis several orders in time.

Some applications regarding the validation of the FSI softwareenvironment finalize the description of the simulation approach showing that the simulation ofcomplex and multidisciplinary problems is laborious and needs a widespread understanding.

Scaling of Performance in Liquid Propellant Rocket Engine Combustors

To find the optimal number of channels of rocket engine thrust chamber, it was found that the optimal channel number is , at which the cooling effect of the thrust chamber cooling channel reaches the best, which can be helpful to design rocket engine thrust chamber. The CFD method was validated via comparing with the available experimental data. Owing to the strong curvature of the cooling channel geometry, the secondary flow reached its strongest level around the throat region. The typical values of pressure drop and temperature difference between the inlet and exit of cooling channel were 2. Besides an optimal number of channels exist, and it is approximately , which can make the effect of heat transfer of cooling channels best with acceptable pressure drop.

Сьюзан приходилось слышать, что сильный страх парализует тело, - теперь она в этом убедилась. Ее мозг мгновенно осознал происходящее, и она, вновь обретя способность двигаться, попятилась назад в темноте с одной только мыслью - бежать. И сразу же услышала треск.

Тогда, при чтении сверху вниз, перед глазами магически возникало тайное послание. С течением времени этот метод преобразования текста был взят на вооружение многими другими и модифицирован, с тем чтобы его труднее было прочитать. Кульминация развития докомпьютерного шифрования пришлась на время Второй мировой войны.

 - С вами все в порядке. Мы уж думали, вы все погибли. Сьюзан посмотрела на него отсутствующим взглядом. - Чед Бринкерхофф, - представился.  - Личный помощник директора.
