Analysis of velocity distribution in an air flow through a thin perforated plate
نویسندگان
چکیده
Modelling air flow in a curved fine perforated plate region was performed by porous zone substitution. This approach significantly simplifies the observed process, thus various limitations appeared. PIV measurements on an experimental test rig were and compared with results from CFD computations.

Flow Distribution inside an Electrostatic Precipitator: Effects of Uniform and Variable Porosity of Perforated Plate
This paper presents a numerical flow model applied to a 3D geometry of an electrostatic precipitator (ESP). The flow simulation is performed by using the computational fluid dynamics (CFD) code FLUENT. Realizable k-ε model for turbulence condition inside the ESP is applied. In the simulation, the perforated plates are modeled as thin porous media of finite thickness with directional permeabilit...
متن کاملFlutter modes of a flexible plate in an air flow
The flutter instability resulting from the interaction of a flexible plate with a fluid flow is experimentally investigated. The present visualizations are obtained with two square plates (i.e. of aspect ratio H/L = 1, see the sketch of the experiment in Fig. 1.) made in a plastic sheet (of flexural rigidity 4.8 10-4 kg m 2 s-2) and of length L = 8 and 21 cm. Experiments are performed in the ho...

با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
15 صفحه اولMHD Casson fluid flow through a vertical plate
In this study, effects of numerous physical quantities like dissipation, thermal radiation, and induced magnetic field on magnetohydrodynamic Casson fluid flow through a vertical plate is addressed. The non-dimensional multivariable governing equations are solved numerically by by means of Runge-Kutta method along with shooting technique. The behavior of velocity, temperature and induced magnet...
متن کاملStructural Analysis of the Exhaust Gas Silencer for the Flow through Perforated and Non-perforated Silencer
To minimize unwanted noise, the exhaust gas of high pressure and high temperature coming out of internal combustion engine passes through silencer. Various types of silencers like absorptive, reactive and resonating, perforated type are widely implemented in actual practice .perforated reactive mufflers have an effective damping capability. This paper deals with comparative structural analysis ...
