Roots blower model for photovoltaic panels

Can a CFD model be used in a Root blower?

A prototype of Roots blower with a backflow design was manufactured to validate the CFD model through the pressure distribution and the mass flow rate. The results showed that the proposed CFD model agreed well with the experimental data.

What is the best method for capturing Root blower flow field?

Out of the three analysed methods, the IPIV technique is the most suitable to capture the Roots blower flow field. However, it has limitations in resolving flow features in regions near gaps and walls. A three-dimensional CFD unsteady simulation model of a Roots blower was established and compared with the IPIV results.

How to design rotor profile of Roots blower?

The shape of rotor-profile of the Roots blower should be designed in such a way that the Roots blower will have high area efficiency with the lowest leakage flow through the clearances. To achieve it, different geometrical shapes are employed to construct the profile of the rotors of the Roots blowers.

How does the optical Root blower work?

The optical Roots blower was mounted in the test rig that allows measurements of pressures, mass flow rates, and power while operating at the variable conditions. The optical access to the Roots blower allowed the use of the PIV laser technique for acquiring velocities inside the main and leakage flow paths.

What is kinematic analysis of a Root blower?

Kinematic analysis of a Roots blower with involute flanks and circular root and tip sections is exp lained. The thermo-fluid model for the blower is described. Two mathematical models have been used to model the blower and its piping system.

What are the main geometrical parameters of the Roots blower?

The main geometrical parameters of the Roots blower. The optical Roots blower was mounted in the test rig that allows measurements of pressures, mass flow rates, and power while operating at the variable conditions.
