Swirl generators are changed to create through-flow with different inlet swirl angles α. In the case of a closed cavity, the swirl generator is replaced by a ring structure, resulting in a cylindrical shroud without any opening. The rig is cooled by water to remove the heat generated by fluid friction.

Module angle optimization¶. The SwerveModuleState class contains a static optimize() (Java) / Optimize() (C++) method that is used to "optimize" the speed and angle setpoint of a given SwerveModuleState to minimize the change in heading. For example, if the angular setpoint of a certain module from inverse kinematics is 90 degrees, but your current angle is -89 degrees, this method will ...

When the tangential angle of air intake is 5°, 10°, 15°, 20° and 25° (see Case B F), the particles exhibit a swirling mixing motion after the air inlet ports, and the number of particles entering the head decreases with the increase of the tangential swirl angle. This is mainly because the larger the tangential swirl angle, the smaller the ...
