Characterization of Bubble Size and Gas Hold up in OBCs Thesis

Characterization of Bubble Size and Gas Hold up in OBCs - Thesis Example Then I plotted the air volume fraction and determined the overall volume of the cylinder it was in (the cylinder lies between the planes mentioned earlier). This provided me with an accurate description of how much air each cylinder between the planes contained. This I used to plot the entrainment fraction. --> Power intensity is directly related to the average sinusoidal velocity of the OBC. Anderson (2009) has not used fixed OBCs. Instead, he has relied on a moving cage and given it power to simulate power intensity. I have tackled this issue by varying the input velocity function for the inlet water. As far as the number of tanks is concerned, please see equation (2) and Hydrodynamic Characterization in Anderson (2009) for a full explanation. Simply put, the number of tanks model is connected to the overall power intensity function that can be manipulated to give an integer value. I used that with expression to give me the values in CFD Post. Can you explain how did you set up physics in cfx-pre to set up the† power intensity verses recovery for different sparger sizes†, as well as â€Å"particle size against entrainment fraction† and â€Å"power intensity versus number of tanks†? These things are obtained from the CFX Post area and not CFX Pre. Power intensity is essentially about increasing or decreasing the inlet water’s velocity to produce a certain range of power intensity. The particle size against entrainment fraction is explained above along with power intensity and number of

Leadership - Coursework Example The key techniques used for developing / improving leadership using theatre and improvisational exercises (for improving and enhancing communication styles); improving and ensuring greater presence (such as increased focus during business presentations, meetings with clients and /or colleagues etc.); using expressive capabilities; and developing and enhancing the art of communicating with the audience (both individuals as well as groups). The article "Choosing strategies for change" presented by Sharon Hill, on the other hand stresses on the significance of managing change within organizations and the various issues faced while initiating new order of things. The article suggests that in order to ensure successful change management within organizations it is imperative to ensure involvement of all employees in the key activities or planning process, since they are the most likely to resist change. Secondly, the article emphasizes on developing strategies specially centered on the type of challenges / resistance likely to be encountered while initiating the change, such as offer training workshops for skill development to the employees. Lastly, one of the most effective ways of initiating the process of change within organizations is taking into consideration the situational factors. This can be achieved by responding to imminent crises situations quickly (Kotter & Schlesinger, 2008). Key techniques used for successful change management include: education (educating the employees), participation (ensuring greater participation of those most likely to resist change), facilitation (offer skills training and workshop), negotiation (offer incentives to influence them to change), and coercion (use threats such as loss of job, promotion or transfer to those resisting the change). 2. Managing change is one of the most difficult and
