2023: Software development for rapid design and prototyping of turbo expanders
Scientists of NRU "MPEI" have developed software (software) for the rapid design and prototyping of turbo expanders, as well as for building their characteristics in non-design modes. The university announced this on December 26, 2023.
The turbo expander is a low-temperature turbine, for which the main task is to lower the gas pressure in order to reduce the temperature of the gas and remove energy from it due to mechanical work by the gas.
The developed software allows you to quickly assess the current power and efficiency of the turbine unit when switching to odd mode without conducting long and expensive tests. The software operates based on the values of parameters at the input and output from the stage, and can determine the necessary rotation speed of the rotor shaft to ensure the maximum possible efficiency and power of the unit for this mode.
 | The software that our scientists have been working on has a lot of weight in various fields of science and technology. For example, the use of such a development greatly simplifies the design of gas distribution stations and allows you to quickly determine the operating mode of the turbo expander on them. With the help of the new software, the operation of the turbines will become more efficient and save the installations from large losses, "said Nikolai Rogalev, rector of MPEI. |  |
The developed software package consists of two modules. The first module allows rapid construction of elements of the stage of radial turbomachines for subsequent prototyping, which greatly simplifies the work of designers and does not require deep knowledge of flow expansion processes. The second module allows you to build a map of the efficiency of turbines in a wide range of input data.
Program modules were developed, tested and registered under the guidance of Arseniy Yastrebova, Associate Professor of the Department of Low Temperatures of the National Research University "MPEI," as part of the work on the project of RNF No. 23-29-00540 "Numerical modeling of phase transitions in the flow section of refrigeration and cryogenic vapor-liquid turbine units."
