2. What is Simulation ? Simulation is the imitation of the operation of a real-world process or system over time. Simulation involves generation of artificial history of a system and drawing inferences from it. The behavior of a system as it evolves over time is studied by developing a simulation model. It takes set of assumptions concerning the operation of the system.

3. When Simulation should be used. Simulations enables the study of experimentation with the internal interactions of complex system, or the subsystem within complex system. Informational, organizational and environment changes can be simulated and the effects of those alternations on the model behavior can be observed. Knowledge gained from designing simulation model can help in suggesting improvement in system . Simulation can be used to experiment with new designs prior to implementation so as to prepare for what may happen.

4. When Simulation should be used. By changing the inputs and observing the resulting outputs, valuable insight may be obtained into which variable are most important and how variable interact. It can be used to verify analytic solutions. Simulation model designed for training allows learning without cost and disruption of on the job learning. The modern systems are so complex that the interactions can be treated only through simulations.

5. When Simulation is not Appropriate When the problem can be solved by common sense . When the problem can be solved analytically. When it is easier to perform direct experiments. If no data is available about the system, not even estimates.

6. Introduction to Flownex Simulation Software

7. Introduction to Flownex Simulation Software Flownex is a systems simulation (one dimensional approach) software that is designed to assist the engineer with the development of systems that require fast, reliable and accurate total system and sub system modeling. By implicitly solving the conservation of mass, momentum and energy equations it is possible to take into account steady and dynamic simulations ( transient ) such as thermal inertias and plant shutdowns. Flownex as a tool enables the engineer to optimize and design thermal hydraulic systems for its characteristic properties (flow rates, pressures etc.). Flownex provides a complete thermal fluid design and analysis solution to meet these challenges.

8. Benefits of Flownex Enables engineers to predict, design and optimize for flow rates, pressures, temperatures and heat transfer rates in fluid systems. Includes anything from ventilation systems and water and gas distribution systems, up to boiler designs and complete power generation cycles. The ability to simulate systems with any combination of liquid, gas, two phase, slurry and mixture flows in both steady state and dynamic cases makes Flownex the most powerful simulation tool of its kind.

10. Software Feature (Graphical User Interface)

11. Software Features GRAPHICAL USER INTERFACE (GUI) GUI is the interface between the user, the solver and the simulation data

12. Ribbon Tabs Select: The “Select” option activates the selector tool and will be used when a network is set up and for selection, resizing, editing, etc.. Interact : Ctrl+Shift+I The “Interact” option activates the interact tool. The interact tool will be used in interact mode where interaction between component and the user is only on a simulation or interface level. Home

13. Paste View Select All Clipboard

14. Simulation Control Solve Steady State The “Solve Steady State” icon solves the network in steady State. Run The “Run” icon solves the network in transient, Designer and Sensitivity solution process dependent on the process selected.

15. Pause The “Pause” icon allows the user to pause the solver during the solution process. Step The “Step” icon allows the user to step the transient solution process, the step will run at the specified time increments Deactivate The “Deactivate” icon allows the user to deactivate the transient solution process. Reset Time The “Reset time” icon allows the user to reset the time of the transient solution process, this will set the solver time back to zero.

16. Design and Analysis Run Designer The “Run Designer” icon allows the user to solve the network in the designer mode. Run Optimiser The “Run Optimiser ” icon allows the user to solve the network in the optimizing mode. Run Sensitivity Analysis The “Run Sensitivity Analysis” icon allows the user to solve the network in the sensitivity analysis mode.

17. 2. Insert Link - Ctrl+Shift+B The “Link” icon activates the “Link Tool” which allows the user to link components on the drawing area. Note that, if Alt is held down and a component is selected with a left click and then a component it can link to is selected, a link will also be created between the components. Data Transfer- Link Ctrl+Shift+D The “Data Transfer Link” icon activates the “Data Transfer Tool” which allows the user to transfer components, solvers or charts between components at specified time intervals.

23. Error Log Window When the user double clicks on an error, the component causing the error is selected on the drawing page, this functionality decreases troubleshooting time. Warnings displayed in the errors window are the warnings encountered during the solution when the project network is being solved.

24. Flow Solver Convergence The Flow Solver Convergence Window progress is graphically shown in the task output window when a network is run/solved. It indicates convergence results for the pressure, continuity and temperature solver.

27. Flownex SE Diagramming System The next step in the basic Flownex network creation procedure is the drawing of the network. The Flownex Diagram System provides the functionality expected of a drawing application like placing and linking components, grid functionality, aligning, spacing etc. The Master Database within the Components window provides a collection of components that may be placed on the drawing page. The user is able to select a component from the Flownex library branch and drag desired component onto the drawing page.

39. Theory Part Turbine: In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or to electrical energy . In its simplest form, a steam turbine consist of a boiler (steam generator), turbine, condenser, feed pump and a variety of auxiliary devices . Steam turbine was invented in 1884 by  Sir Charles Parsons , whose first model was connected to a dynamo that generated 7.5 kW (10 hp ) of electricity

40. WORKING PRINCIPLE OF STEAM TURBINE Working principle of steam turbine depends on the dynamic action of steam. A high-velocity steam is coming from the nozzles and it strikes the rotating blades which are fitted on a disc mounted on a shaft. This high-velocity steam produces dynamic pressure on the blades in which blades and shaft both start to rotate in the same direction. Basically,in a steam turbine pressure energy of steam extracts and then it converted into kinetic energy by allowing the steam to flow through the nozzles. The conversion of kinetic energy does mechanical work to the rotor blades and the rotor is connected to a steam turbine generator which acts as a mediator . Turbine generator collects mechanical energy from the rotor and converts into electrical energy.
