Irreversibility of the Direct and Counter Impinging Liquid Jet onto Profiled Heated Cavity

Gas Jet Impinging on Liquid Surface: Cavity Shape Modelling and Video-based Estimation

A water model is studied to simulate physical phenomena in the LD steel converter. The depression in the liquid, due to the impinging gas jet, is measured by means of a video camera. Image processing tools together with a nonlinear mathematical model based on the physics of the liquid-gas system, are used to describe the cavity profile. The properties of the model are investigated. A quantifica...

Investigation of the interaction of a turbulent impinging jet and a heated, rotating disk

Transverse Jet-Cavity Interactions with the Influence of an Impinging Shock

For high-speed air breathing engines, fuel injection and subsequent mixing with air is paramount for combustion. The high freestream velocity poses a great challenge to efficient mixing both in macroscale and microscale. Utilising cavities downstream of fuel injection locations, as a means to hold the flow and stabilise the combustion, is one mechanism which has attracted much attention, requir...

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...

Irreversibility Analysis of MHD Buoyancy-Driven Variable Viscosity Liquid Film along an Inclined Heated Plate Convective Cooling

Analysis of intrinsic irreversibility and heat transfer in a buoyancy-driven changeable viscosity liquid along an incline heated wall with convective cooling taking into consideration the heated isothermal and isoflux wall is investigated. By Newton’s law of cooling, we assumed the free surface exchange heat with environment and fluid viscosity is exponentially dependent on temperature. Appropr...
