Modular structure of the LV software

We often refer to the modular structure of our software package. Maybe you have already wondered what this means.
Long story short, each module reflects a specific calculation for a specific topic, such as calculating theheat transfer coefficient in a tube flow.

The modular design gives you the possibility to freely calculate your specific apparatus. It does not matter if we have taken your design into account when creating the software.

For example, you want an estimate of how big your heat exchanger will be. For this you now need your media on both sides, the material of the heat exchanger and the heat transfer coefficients on both sides.

To do this, select the modules BIL (energy balance and heat transfer), G1((heat transfer coefficient in tubes) and possibly G8(heat transfer coefficients in tube bundles) and the corresponding modules for your media properties (perhaps H2O on both sides). In BIL you would enter your requirements (mass flow, temperatures, geometric data).

In the physical properties modules you would have as input the average temperature (inlet-outlet) and the pressure. Their properties and geometry data are the same as in modules G1 and G8 for heat transfer calculations. The properties and the heat transfer coefficients are the inputs for BIL.

With all of this together, you would then have an estimate of whether or not your required area matches the actual area.

For your convenience, there is something we call linking variables. The purpose of this is to transfer the changes in one module to the other when you link several modules. In the examples above, you would link the temperature and pressure of BIL to the physical properties modules.

Of course, you can also use our WTS module for shell-and-tube heat exchangers or AC for air coolers, which will do all the work for you.
