Chemical Engineering - Lab Report Example This is done in order to understand regime flow of gas-liquid and liquid-solid fluidization. Ceramic Raschig rings, air, and water are used as the respective solid, gas and liquid phases respectively. The experiment was done in a 2m-height, 100 mm ID vertical Plexiglas column. The column has 3 parts; the part of gas-liquid disengagement, test part and part of the gas-liquid distribution. Measurements of Bed pressure were made to estimate the least velocity of liquid fluidization. By maintaining the velocity of the gas, the liquid velocity is altered and the influence on expansion ratio, pressure drop, and least velocity of liquid fluidization was calculated for static bed height and various particle size and. Gas-Liquid-Solid-Phase fluidized beds are in most cases applicable in physical processes (Murayama, 2005). For instance, the process of a fixed bed, where both countercurrent and concurrent liquid and gas flow are permitted, and for either of these both flow of bubble, in which the gas flow is discrete, and dribble and the liquid is the continuous phase. This way, the gas forms a continuous phase and the liquid more or less dispersed (Epstein, 2009). Three-phase fluidization can be categorized largely into 4 modes. The first mode is mode I-a; co-current gas-liquid-solid –phase fluidization with liquid as the continuous phase co-current three-phase fluidization. The second mode is mode-I-b that is featured by gas as the continuous phase. The third being mode II-a; inverse three-phase fluidization. The fourth, TCA mode II-b fluidization has characteristics of a contact absorber that is turbulent. Modes II-b and II-a are attained by a flow of liquid and gas that is countercurrent. Amongst which the most striking one is the co-current three-phase fluidization with the liquid as the continuous phase (Murayama, 2005).

How collaborative media technologies can be used in the planning, Essay

How collaborative media technologies can be used in the planning, design, development and delivery of multimedia projects - Essay Example vious limitations in accessing media and sharing methods are now resolved through the implementation of the contemporary collaborative media and associated sharing and recommendation methods, because, the contemporary collaborative media methods utilize agents on media players/devices to enlarge the extent of media sharing situations (Lamoureux & Rehak, 2007). The method supports a client in finding out media items and which are appealing to the user. The collaborative media commendation and sharing method contemporaneously find out a users media preferences foundational on media stored on a group of media devices as well as suggest media for potential sharing foundational on these assessable regarding user preferences (Diercks-O’Brien & Sharratt, 2002). The emergence of new technology for the development, designing and planning has offered a huge number of advantages to developers. In addition, at the present, we have a lot of applications those are helpful in collaboration a nd mutual data sharing. A project is a collection of various similar activities. All the activities are involved with each other, especially in multimedia projects. So the collaboration is the main thing in the successful implementation or completion of a multimedia project. The purpose of this paper is to analyze the new and more effective aspects of the collaboration technology and it’s utilization for the better project development and implementation. This paper presents a detailed analysis and investigation of the collaborative media technologies that can be used in the planning, designing, development, and delivery of multimedia projects. According to Kellerman (2009) a multimedia project is a substantial task that requires effective planning, management and organization of tasks. In this scenario we need to pay greater attention to management and handling of the multimedia project. A successful outcome relies on the time as well as effort that we spend in planning the project in an
