in this paper the problem on “magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by n ahmad et.al.[7]” has been recapitulated using jenkin’s model [4] with the additional effect of squeeze velocity of the above plate. it is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (refer equation(2.2)). this paper re...
Syngas (for synthetic gas) is a well known gaseous biofuel, also as producer gas or wood gas. It composed mainly of N2, CO2, CO, H2 and CH4, with varying shares depending on the gasification process biomass source. When syngas used in Internal Combustion engines for stationary electricity generation, operation modes have to be adapted. The problem that, moment, combustion parameters complex com...
Abstract. Convective clouds are common and play a major role in Earth's water cycle energy balance; they may even develop into storms cause severe rainfall events. To understand the convective cloud development process, this study investigates impact of aerosols on by considering influence both topography diurnal variation radiation. By combining texture analysis, clustering, thresholding metho...
according to flexibility of pneumatic conveying systems with respect to other types of transmission systems, this system has wide application in industry and agriculture processes. one important application of this system is in the loading and unloading tankers and powdery bulk materials such as trucks carrying cement, plaster and sand. conveying efficiency is associated with pressure, which in...
A new dual-frequency (Ku and Ka band) nadir-pointing Doppler radar on the high-altitude NASA ER-2 aircraft, called the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP), has collected data over severe thunderstorms in Oklahoma and Kansas during the Midlatitude Continental Convective Clouds Experiment (MC3E). The overarching motivation for this study is to understand the behavior of...
7 Responses of shallow cumuli to large-scale temperature/moisture perturbations are examined 8 through diagnostics of large-eddy-simulations (LES) of the undisturbed Barbados Oceano9 graphic and Meteorological Experiment (BOMEX) case and a stochastic parcel model. The 10 perturbations are added instantaneously and allowed to evolve freely afterwards. The par11 cel model reproduces most of the c...
