“…In paper [6], advancements in numerical algorithms, computer hardware, and geometric preprocessing have enabled CFD to simulate the flow field around aerospace vehicles with all its geometrical complexities. This matured technology is not only explaining the complex flow physics, but also providing important design inputs for various aerospace vehicle including fighter and transport aircraft, launch vehicles and missiles.…”

— The objective of the work is to compare between convergent, convergent-divergent nozzle and to analyse which has better performance in a miniature aircraft having vertical lift system. Comparison is done by having 2° and 4° attack angle at a free stream mach no 0.8 and to find the variation of pressures around, drag. CFD analysis has been performed for the miniature aircraft. Pressure forces, viscous forces, pressure coefficient and viscous coefficient are found for convergent nozzle and convergent-divergent nozzle. Also pressure variation at 2 ° and 4 ° angle of attack for Airfoil types AIG(smart fish) and NACA(Conventional) are found. It was found convergent-divergent nozzle is best suited with vertical lift having exit jet velocity 2700m/s. It is also found that airfoil produce less drag when attack angle is 4 °

This paper presents the computational investigation of air flow over an aircraft at realistic speeds while demonstrating the importance of extending the existing analysis to the complete airplane and how pivotal it is in improving its in-flight performance. The study is done for F16 and F22 aircraft using ANSYS Fluent (19.2) to obtain pressure distribution, shear stress distribution and temperature variation on the complete surface of the aircraft. Since the front section of the aircraft is prone to direct initial impact of surrounding environment, this portion is also examined. Here, as the speed is doubled from Mach 1 to Mach 2, a rise in the value of all the three variables is noticed for the F16 aircraft, whereas the pressure distribution for F22 aircraft shows strange behaviour for the highest speed (Mach 2). On comparing the results over the whole surface, it is seen that F16 experiences smaller pressure (29% lower for Mach 1 and 30% for Mach 2), temperature (9.5% lower for Mach 1 and 30% for Mach 2) and shear stress relative to F22 and the stress shows a huge change (90% lower for Mach 1 and 83% for Mach 2). Results of the present study imply that the design of the aircraft highly influences its performance as the parameters discussed touch their limits.

In spite of the fact that it is the most imperative and crucial industry, oil production is still facing problems which represent challenges to producers and operators. This paper presents brief highlights on CFD simulations of some problems associated with oil/water and oil/gas flows carried out by a specialized research team in Universiti Teknologi PETRONAS. Three particular problems have been modelled, simulated and analysed. The first problem is on oil/water mixture flow in the production zone in the downhole; the second is on separation of the oil/water by hydrocyclone separator in the downhole; while the third problem is on the two phase oil/gas flowing in a pipe and the resulted slug flow. For each case, the layout of the procedure of the model setup is explained, and the numerical procedure is outlined in terms of the software used, the mesh generation and its independency criteria. For each case, the validation procedure has been mentioned and in the last part of each case, some samples of results are presented and briefly discussed.
