1/10/2024 0 Comments Wolfram player download![]() The screencast video at shows how to use this Demonstration, and the video at explains the cycle. Where is the net work (kJ/kg), and is heat added (kJ/kg). The turbine efficiency indicates the turbine irreversibility and is the ratio of irreversible work to reversible work. Get your free Mathematica Online trial license. The change in enthalpy for the reversible turbine is the work for the reversible process. The use of Mathematica Online, the online version of Wolfram Mathematica based on the Wolfram Cloud. If, and is found in the superheated steam tables at and. Where is the fraction of vapor (quality), and the superscripts and refer to saturated liquid and saturated vapor.ĭepending on the quality of the exiting steam, is obtained from either the saturated steam tables or the superheated steam tables. If at, then the outlet steam is at saturation temperature and consists of liquid and vapor. If at, then the reversible outlet state is superheated. A reversible steam turbine is isentropic, so, where is the entropy of the steam exiting a reversible turbine. From these conditions the enthalpy (kJ/kg) and entropy (kJ/) are obtained from the superheated steam tables. The inlet temperature to the turbine, (☌) is set you can vary the inlet and outlet pressures (MPa). Select "Rankine cycle" to view a schematic of the cycle, and select "turbine" to show the inlet and outlet conditions for the turbine and the work generated. The irreversible turbine pathway ( ) is the dashed black line on the diagram the reversible turbine pathway is the orange dashed line. Use a slider to vary the turbine efficiency, which is the ratio of work produced by the turbine to the work produced by a reversible turbine between the same inlet and outlet pressures. ![]() Use sliders to select the inlet pressure to the turbine and one of four outlet pressures. It's like replacing your car (Mathematica 10) with your garage (Wolfram Desktop). Wolfram Desktop will not replace Mathematica 10 as they are not comparable. A desktop interface to your Wolfram Programming Cloud subscription. Select " diagram" to see the cycle on a pressure-enthalpy diagram. It is a program that you can download, as part of an eligible Wolfram Programming Cloud subscription. ![]() After the steam is condensed (5), a pump compresses the liquid water to high pressure (1). The steam exits the turbine at a lower pressure and temperature as either superheated steam or steam with a vapor quality (4). Wolfram CDF Player provides users with the possibility of interacting with applications from Wolfram Demonstrations Project, of exploring Mathematica files. The superheated steam is fed to a turbine, where it expands and generates mechanical work. In a Rankine cycle, high-pressure liquid water (1) enters a boiler where it is heated to saturation temperature (2), vaporized, and superheated (3).
