In aerodynamics study, whenever there is a flat/blunt face, it will result in the maximum drag effect on flat body. these types of problems, splitter plates have found significant role reducing force. The plate separate/bifurcate flow at front face present study aims to find fluid flows over body by varying length plate. pressure and Mach number effects near surface Also, crucial for higher vel...
I Circa 1.1 Ga granitic magmatism in Texas was manifested as two compositional groups: (1) the 1.12 Ga Red Bluff granitic suite in west Texas; and (2) 1.12-1.07 Ga granites of the Llano uplift of central Texas. Both suites share some characteristics typical of 'anorogenic' granites (e.g. potassiumand iron-rich bulk compositions, Fe-rich hydrous silicates, emplacement conditions involving low ox...
Advanced combustion strategies for gas turbine applications, such as lean burn operation, have been shown to be effective in reducing NOx emissions and increasing fuel efficiency. However, systems are susceptible thermo-acoustic instabilities which can lead deterioration engine performance. This paper will focus on one of the common industrial techniques controlling instabilities, secondary inj...
Statistical flow modelling does not provide enough detail for many flows of engineering relevance in which unsteadiness is a central feature. This applies particularly to bluff-bodies and assemblies comprising bluff components for which the resolution of peak forces, unsteady loading, acoustics and fatigue are of interest as part of the design process. An example application which has been stud...
در تحقیق حاضر، به مطالعه عددی پایداری شعله در سرعت های بالا با استفاده از روش ایجاد ناحیه بازچرخشی جریان از طریق شعله نگهدار bluff-body vee-gutter در یک برنر دو بعدی متقارن محوری سوخت گازی متان و اکسنده هوا در نسبت های انسداد انفرادی مختلف و نیز موتور رم جت سوخت مایع 26 اینچی آزمایشگاه پیشرانش لوئیس ناسا پرداخته شده است. نتایج حاکی از آن است که در برنر سوخت گازی در سرعت های بالای هوای ورودی (در...
