Welcome to TEST - a visual platform to analyze thermofluids problems, verify hand calculations, pursue what-if scenarios, visualize thermal systems, and engage in a life-long journey to master thermodynamics.

Created for learning, teaching, and practicing thermodynamics, TEST offers analysis tools for property evaluation of hundreds of working substances, energy, entropy, and exergy analysis of open and closed systems, IC engines, gas and vapor power cycles, refrigeration, HVAC, combustion, chemical equilibrium, and gas dynamics. Browse the Examples or Problems module to check out some of the problems TEST can help you analyze.

Beside the daemons - dedicated web-based calculators with a friendly graphical interface - you will find other useful modules such as the animation library, video clips, traditional charts and tables, manual and TEST solutions to hundreds of engineering problems, and fifteen chapters of examples and problems to supplement any thermodynamics textbook.

Go through the VisualTour or, better, the hands-on Tutorial, specifically the Getting Started and My First TEST Solution sections, before you create an account (takes less than a minute) and start exploring TEST. Once you conclude that TEST can be a useful tool for you, visit the myAccount page to upgrade your account, order a CD for local installation, or request a site license for your institution. TEST is freely distributed to educators and students of any academic institution.
