Current trends towards renewable energy and other alternative sources and the energy pricing policy do not favor investment in large energy units. Local energy sources with heat recovery , and cogeneration for the production of are increasingly being used. From these compressors, micro turbines, single-stage expanders to conventional multi-stage turbines, all are used in these machines.

TechSim Engineering provides complete engineering from designing and optimizing the cycle to designing the jet parts - impellers, nozzles, diffusers and output cabinets, ensuring their strength and dynamic control:

Thermal Calculations

When designing larger power turbines, the construction currently requires specifications for increasing temperature parameters of the working medium as well as for rapid start-ups and shutdowns, especially when used as an industrial power source or in solar power plants. Compliance with these requirements needs accurate temperature field prediction due to possible large temperature gradients. TechSim Engineering offers the following types of calculations in this area:
