STF Flow and Mathematical Application of Nuclear Reactor.

      Аннотация: Stretch-Twist-Fold (STF) has its application in fluid mechanics concentrated towards aerospace. The Stretch-Twist-Fold flow is a three-dimensional 3D system of ordinary differential equation ODE with quadratic nonlinearities. In space, any fluid can be de-tracked easily so a magnetic field is required to compel the fluid to be in the same orbit and this method is called STF system. The studies of the magnetic fields of the Earth and Sun as well as those of other planets, stars, and galaxies, have a long history with rich and comprehensive literature.Up till now, few numbers of review articles and books dedicated to the dynamo theories have been published. However,this book will provide the good sprite of this field. The research is also conducted on the mathematical modeling of nuclear reactor analysis by using specialized nuclear reactor codes. In this work, we have developed a mathematical model for thermal hydraulic analysis of nuclear reactor core. This modified nuclear code is applicable to the thermal analysis of the reactor which is very important to determine the design of the reactor.
