Engineering Equation Solver EES Cengel Thermo Isol

If you are looking for a powerful and versatile tool to solve engineering equations involving thermodynamic and transport properties, you might want to check out Engineering Equation Solver (EES). EES is a general equation-solving program that can numerically solve thousands of coupled non-linear algebraic and differential equations. It can also perform various tasks such as optimization, uncertainty analysis, regression, unit conversion, and plotting.



EES is especially useful for thermo iso problems, which are problems that involve constant temperature or constant entropy processes. Thermo iso problems are common in engineering applications such as heat engines, refrigeration cycles, compressors, turbines, and heat exchangers. EES can help you solve these problems by providing high accuracy thermodynamic and transport functions for hundreds of fluids. You can also use EES to generate property diagrams such as T-s, P-v, P-h, and P-T plots.

How to Use EES for Thermo Iso Problems

To use EES for thermo iso problems, you need to follow these steps:




Download and install EES from https://fchartsoftware.com/ees/. You can choose from different types of licenses depending on your needs and budget.
Launch EES and enter your equations in the main window. You can enter the equations in any order and use any variable names. You can also use built-in functions and constants provided by EES.
Specify the thermodynamic and transport properties of the fluids involved in your problem. You can do this by using the Thermophysical menu or by typing the name of the fluid followed by a dot and the property name. For example, if you want to specify the enthalpy of water at 300 K and 1 bar, you can type Water.h(300[C],1[bar]).
Solve your equations by clicking the Solve button or pressing F2. EES will display the values of the unknown variables in the Solution window.
Plot your results by using the Plot menu or by typing plot commands in the main window. You can choose from different types of plots such as 2-D, 3-D, contour, and property plots. You can also customize your plots by changing the axes, labels, colors, symbols, and legends.
Save your work by using the File menu or by pressing Ctrl+S. You can also export your results to other formats such as LaTeX, PDF, or Excel.


Example of Using EES for Thermo Iso Problems

To illustrate how to use EES for thermo iso problems, let us consider a simple example of an ideal gas undergoing a reversible adiabatic expansion. The initial state of the gas is P1 = 5 bar, T1 = 400 K, and V1 = 0.1 m3. The final state of the gas is P2 = 1 bar. We want to find the final temperature T2, the final volume V2, and the work done by the gas W.



To solve this problem using EES, we can enter the following equations in the main window:



P1*V1^k = P2*V2^k Adiabatic process
W = (P1*V1 - P2*V2)/(k-1) Work done by gas
k = Cp/Cv Ratio of specific heats
Cp = Air.Cp(T) Specific heat at constant pressure
Cv = Air.Cv(T) Specific heat at constant volume
T = (T1 + T2)/2 Average temperature


We can also specify the values of the known variables:



P1 = 5 [bar]
T1 = 400 [K]
V1 = 0.1 [m3]
P2 = 1 [bar]


After solving these equations using EES, we get the following results:



T2 = 223.6 [K]
V2 = 0.464 [m3]
W = -36.8 [kJ]
k = 1.4
Cp = 1.02 [kJ/kg-K]
Cv = 0.72 [kJ/kg-K]
T = 311.8 [K]


We can also plot the P-v diagram of this process using EES by typing the following plot command in the main window:



Plot P(V), V=V1..V2


This will generate a plot like this:









Conclusion

EES is a powerful and versatile tool for solving engineering equations involving thermodynamic and transport properties. It can help you solve thermo iso problems by providing high accuracy thermodynamic and transport functions for hundreds of fluids. You can also use EES to generate property diagrams such as T-s, P-v, P-h, and P-T plots.
