Problems solved by technology
[0004] The centrifugal fan system is a complex nonlinear thermodynamic system. When the centrifugal fan, pipe network, and valves constitute a huge nonlinear thermodynamic system, the coupling of components makes the internal heat and mass transfer of the system complicated, making the dynamic transfer of parameters and the decoupling of equations variable. difficult
Many scholars have done some research on centrifugal fans, pipe networks, and valves, but there is a lack of dynamic simulation research on the overall modeling of centrifugal fan systems, especially the lack of in-depth component mechanism simulation research and system dynamic simulation methods.

The invention discloses a centrifugal fan system dynamic simulation method and system based on MATLAB, corresponding characteristic parameter interfaces are reserved in parts such as a centrifugal fan, a pipe network, a valve and the like, and users can set characteristic parameters of simulation modules such as the centrifugal fan, the pipe network, the valve and the like according to the actual background; and a dynamic simulation model is built according to the actual connection condition of the centrifugal fan system, so that the method has certain universality. Along with improvement of performance curves of various types of centrifugal fans, the method can be applied to establish a module library of common ventilators, air blowers, compressors, valves and pipe networks in a dynamic simulation system. In a project, a user can complete centrifugal fan type selection and ventilation system design according to design requirements, and a project implementation scheme is determined by comparing and analyzing dynamic simulation results.
Description
technical field [0001] The invention belongs to the field of gas centrifugal fan systems, and in particular relates to a dynamic simulation method and system for a centrifugal fan system based on MATLAB. Background technique [0002] Centrifugal fan is a kind of important rotating machinery, which plays an important role in petroleum, chemical industry, aviation, metallurgy, national defense, energy and other fields. The principle is as follows: the temperature of the working medium gas is accelerated by the impeller, and then enters the downstream equipment after being boosted by the diffuser. According to the strength of its pressure rise ability, it can be divided into ventilator, blower and compressor. In engineering, centrifugal fans are usually combined with pipe networks and valves to form a centrifugal fan system. As the core of the system, the centrifugal fan works on the gas working medium, and realizes the compression, transportation and distribution of the work...
