WebAs the name implies, shear stress refers to the action of a force applied to a material, as indicated by equation 1. 𝞽 = F/A (1) where 𝞽 is the shear stress, F is the applied force, and A is the cross-sectional area parallel to the direction of the applied force. The above equation gives the average shear stress per unit area. WebAug 15, 2024 · The variation of flow rate causes a retardation effect from the inlet to the cylinder wall, which leads to a minimum of gas phase around the bottom dead center, as shown from 252° CA to 576° CA in Figure 12. The reason is that near the bottom dead center of the intake stroke the gas in the coolant condensates and transfers heat to the in ...
