Dynamics of pressure pulsations in thin annular gap
نویسندگان
چکیده
Fluid pulsations can significantly influence behavior of bearings or sealing parts hydraulic machines and therefore their operation. In this contribution, an analytical approach to solve pressure dynamics is compared with a computational solution using acoustic simulation in ANSYS Mechanical FEM package. Studied problem simplified annular gap the are excited either from one annulus end excitation made by movement inner cylindrical surface perpendicularly its axis. Excitation on have angle dependent phase. This geometry allows linearization governing equations so solvable analytically. Compressibility was incorporated eigen frequencies for both methods were evaluated compared. Also added fluid effects studied evaluated.

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...
Flow and heat transfer inside thin films supported by soft seals in the presence of internal and external pressure pulsations
The effects of both external squeezing and internal pressure pulsations are studied on flow and heat transfer inside non-isothermal and incompressible thin films supported by soft seals. The laminar governing equations are non-dimensionalized and reduced to simpler forms. The upper plate displacement is related to the internal pressure through the elastic behavior of the supporting seals. The f...
متن کاملUltrasonic Pulsations of Pressure in a Water Jet Cutting Tool
Original scientific paper Water flow in a tool for water jet cleaning and cutting is evaluated in this paper. There are ultrasonic pulsations of high pressure in the given domain. The efficiency of the amplification of high pressure pulsations in the transitional space between larger and smaller pipes is analysed. Three types of transitional spaces are compared in the paper: step change, conica...
