Key words Laval nozzle, thrust-vectoring, shape and CFD Abstract:This study employed Computational Fluid Dynamics, CFD solution to configure the entire shape of the nozzle.
Then with a two-dimensional approach and coded FORTRAN programs, the convergent portion was handled with time matching CFD while the divergent portion was handled with space matching CFD.
However, in this study, we decided to consider the convergent and divergent portions separately and then merge the portions: while the convergent section is dealt with using time matching CFD, the divergent portion is handled with space matching CFD.
This post processing technique demonstrates that its absence often leads to highly non-optimal simulation strategies and errors in the simulation are found (if detected at all) after a Ssimulation has been run completely.

CFD analysis of Heat transfer characteristics of Helical Coil Heat Exchangers R.
The simulation is carried out by keeping the cold water flow rate constant at 200 LPH (litre/h) and varying the hot water flow rate from 50 LPH to 200 LPH.
The results and contours are obtained from Ansys CFD Post.
This shows the conformity of the CFD results presented in this work.
The simulation results indicate that the heat transfer parameters like Nusselt number and heat transfer coefficient are higher for the helical tube in tube than the straight tube in tube.

Pipe reactor simulation of biological growth was investigated based on computational fluid dynamics (CFD) and reaction dynamics in single-phase laminar incompressible flow with the open-source software, OpenFOAM.
Introduction Computational fluid dynamics (CFD) is a very flourish field in the last decade since the software of CFD becomes more and more popular in the engineering.
But, CFD is limited in chemical engineering in a way because mass transfer and reaction have not been combined with CFD properly at present.
And the reaction combined with CFD was summerized by R.
OpenFOAM is a free, open source CFD software package produced by OpenCFD Ltd.
