Absim Absorption Simulation Download Zip ~UPD~



What is ABSIM and How to Download It?




If you are interested in simulating absorption systems, you may have heard of ABSIM, a computer code that was developed by The Oak Ridge National Laboratory in the 1980s and 1990s. ABSIM stands for ABsorption SIMulation, and it is a powerful tool that allows you to investigate various cycle configurations and working fluids, calculate their operating parameters, predict their performance, and compare them with each other on a uniform basis.

ABSIM is based on a modular structure, which means that it consists of unit subroutines that represent the components of the absorption system, such as heat exchangers, pumps, valves, absorbers, generators, etc. A main program calls these subroutines and links them together according to the cycle diagram that you provide. Then, a mathematical solver routine solves the system of equations for the entire cycle simultaneously. ABSIM also has a database of property subroutines that provide thermodynamic properties of the working fluids.


Why Use ABSIM?




ABSIM is a very useful and accurate tool for researchers and engineers who want to design and optimize absorption systems. With ABSIM, you can simulate complex cycles with different working fluids, such as lithium bromide-water, ammonia-water, methanol-water, etc. You can also simulate advanced cycles, such as double-, triple- and quadruple-effect cycles, GAX (generator-absorber heat exchange) cycles, branched GAX cycles, and VX (vapor exchange) cycles. ABSIM can help you to evaluate the performance of your system under different operating conditions, such as temperature, pressure, flow rate, concentration, etc.


ABSIM can also help you to compare different cycle configurations and working fluids on a uniform basis. You can use ABSIM to perform parametric studies, sensitivity analyses, optimization studies, etc. ABSIM can also generate plots and tables of the results for easy visualization and interpretation.

What are the Challenges of ABSIM?




ABSIM is a powerful and versatile software tool for simulation of absorption systems, but it also has some challenges and limitations that users should be aware of. Some of these challenges are:


  • ABSIM requires a good initial guess for the solver to converge, especially for complex and nonlinear cycles. If the initial guess is too far from the true solution, the solver may fail to converge or converge to a wrong solution. ABSIM has an automatic initial guess generating algorithm that can help users to find a suitable initial guess, but it is not foolproof and may not work for some cases.



  • ABSIM may not have all the components and working fluids that users need for their simulation projects. ABSIM has a large database of property subroutines for various working fluids, but it may not cover all the possible fluids that users may want to use. ABSIM also has a variety of components that users can choose from, but it may not have some specific components that users may need. Users can add their own components and working fluids to ABSIM by writing their own subroutines, but this requires programming skills and knowledge of the ABSIM structure.



  • ABSIM may not be compatible with some other software tools that users may want to use for their simulation projects. ABSIM can export the results to a file in CSV format, but it may not be able to import data from other sources or formats. ABSIM can also generate plots and tables of the results, but it may not be able to create advanced graphics or animations that users may want to use for presentation or publication purposes.
