.Unfortunately, CAE is no longer granted the ability to offer EES for download.Here is a description of EES (from Professor S. Klein's website). EES (pronounced 'ease') is an acronym for Engineering Equation Solver. The basic function provided by EES is the solution of a set of algebraic equations. EES can efficiently solve thousands of coupled non-linear algebraic equations. EES can also be used to solve initial value differential equations. EES provides publication-quality plots, linear and non-linear regression, optimization, unit conversion and consistency checking, and uncertainty analyses.
Built-in functions are provided for thermodynamic and transport properties of many substances, including steam, air, refrigerants, cryogenic fluids, JANAF table gases, hydrocarbons and psychrometrics. Additional property data can be added. EES also allows user-written functions, procedures, modules, and tabular data.

Klein All rights reserved. Starting EES The default installation program will create a directory named C: EES32 in which the EES files are placed. The EES program icon shown above will identify both the program and EES files.
Double-clicking the left mouse button on the EES program or file icon will start the program. If you double-clicked on an EES file, that file will be automatically loaded.
Chapter 1 Getting Started Background Information EES begins by displaying a dialog window that shows registration information, the version number and other information. The version number and registration information will be needed if you request technical support. If this is your first time running EES, you may wish to specify the default unit system and other default settings.
Clicking the Preferences button will take you to the Preferences dialog where the options can be changed and stored. Alternatively, click the Continue button to dismiss the dialog window and start with an empty EES documents. Detailed help is available at any point in EES. Pressing the F1 key will bring up a Help window relating to the foremost window. Clicking the Contents button will present the Help index shown below. Clicking on an underlined word (shown in green on color monitors) will provide help relating to that subject. Note that a toolbar is provided below the menu bar.
The toolbar contains small buttons which provide rapid access to many of the most frequently used EES menu commands. If you move the cursor over a button and wait for a few seconds, a few words will appear to explain the function of that button.
The toolbar can be hidden, if you wish, with a control in the Preferences dialog (Options menu). The System menu represented by the EES icon appears above the file menu. The System menu is not part of EES, but rather a feature of the Windows Operating System. It holds commands that allow window moving, resizing, and switching to other applications. The File menu provides commands for loading, merging and saving work files and libraries, and printing. The Edit menu provides the editing commands to cut, copy, and paste information The Search menu provides Find and Replace commands for use in the Equations window. The Options menu provides commands for setting the guess values and bounds of variables, the unit system, default information, and program preferences.
A command is also provided for displaying information on built-in and user-supplied functions. The Calculate menu contains the commands to check, format and solve the equation set. The Tables menu contains commands to set up and alter the contents of the Parametric and Lookup Tables and to do linear regression on the data in these tables.
The Parametric Table, similar to a spreadsheet, allows the equation set to be solved repeatedly while varying the values of one or more variables. The Lookup table holds user-supplied data which can be interpolated and used in the solution of the equation set. The Plot menu provides commands to modify an existing plot or prepare a new plot of data in the Parametric, Lookup, or Array tables. Curve-fitting capability is also provided. The Windows menu provides a convenient method of bringing any of the EES windows to the front or to organize the windows. The Help menu provides commands for accessing the online help documentation. Chapter 1 Getting Started case letters and the sign (or.) is used to signify raising to a power The basic capability provided by EES is the solution of a set of non-linear algebraic equations.
To demonstrate this capability, start EES and enter this simple example problem in the Equations window. Note that EES makes no distinction between upper and lower. Getting Started Chapter 1 An Example Thermodynamics Problem A simple thermodynamics problem will be set up and solved in this section to illustrate the property function access and equation solving capability of EES.
The problem, typical of that which may be encountered in an undergraduate thermodynamics course, is as follows. Refrigerant-134a enters a valve at 700 kPa, 50°C with a velocity of 15 m/s. At the exit of the valve, the pressure is 300 kPa. The inlet and outlet fluid areas are both 0.0110 m2. Determine the temperature, mass flow rate and velocity at the valve exit. State 1 T = 50°C P = 700 Vel = 15 m/s State 2 T =? P = 300 kPa Vel =?
The system is the valve. The mass flow is steady, so that the mass balance is: To solve this problem, it is necessary to choose a system and then apply mass and energy m = mass flowrate kg/s A = cross-sectional area m2 Vel = velocity m/s v = specific volume m3/kg The valve is assumed to be well-insulated with no moving parts. The heat and work effects are both zero. A steady-state energy balance on the valve is: 1 2 2 Vel Velmh m h (5). Sansui sd 7000 manual.
Have been made and the units in each equation are dimensionally consistent. The Check Units command (Calculate menu) initiates the unit checking capability manually. From relationships between the properties of R134a: problem with the kinetic energy terms and judge their importance Ordinarily, the terms containing velocity are neglected, primarily because the kinetic energy effects are usually small and also because these terms make the problem difficult to solve. However, with EES, the computational difficulty is not a factor. The user can solve the Vel2, h1, v1, h2, v2, T2. Since there are 9 equations, the solution to the problem is defined. It is now only necessary to solve the equations.
This is where EES can help. Start EES and select the New command from the File menu. A blank Equations window will appear. Before entering the equations, however, set the unit system for the built-in thermophysical properties functions. To view or change the unit system, select Unit System from the Options menu.
Getting Started Chapter 1 Click the OK button (or press the Return key) to accept the unit system settings EES is initially configured to be in SI units with T in °C, P in kPa, energy units in kJ and specific property values in their customary units on a mass basis. These defaults may have been changed during a previous use.
