The changing relation among the penetration and turbine angular velocity
the fore-and-after pressure difference of back boltless baffle and pressure of blade imposed on the baffle was discussed based on the finite element platform.The equation of the relation mentioned above was established by the least square method.According to the deformation coordination of baffle and turbine
the relational equation of rotational speed
fore-and-after pressure difference of boltless baffles and available pressure was concluded.
