Attribute-ID	ventilation_loss_torque_in_mesh_maurer
Numeric ID	18636
Value Type	PMTechValue

The ventilation power loss P_{VZ0_V,mesh} or the ventilation torque loss T_VV,mesh for injection lubrication is the part of ventilation loss according to Maurer caused by the mating gear when the wheels engage. The ventilation torque loss T_VV,mesh are calculated for the driven wheel.

$T_{V V} = 1, 17 \cdot 10^{- 6} \cdot v_{t}^{1, 95} \cdot u^{0, 73} \cdot b^{1, 37} \cdot F_{W a n d} \cdot F_{O i l}$

$T_{V V, m e s h} = \{\begin{cases} \frac{1}{u} \cdot T_{V V}, g e a r 1 (p i n i o n) i s d r i v e n \\ T_{V V}, g e a r 2 (w h e e l) i s d r i v e n \end{cases}$

$P_{V Z 0_V, m e s h} = 2 \cdot π \cdot n \cdot T_{V V, m e s h}$
