The motion velocity of a fluid particle changes only in a direction consistent with the flow direction; this type of flow is known as （） flow ； Flow in which the velocity of fluid particles changes only in a direction perpendicular to the flow direction is called （ ） flow. Stretching, Shearing
When the velocity of a fluid particle changes only in a direction consistent with the flow direction, it is referred to as (stretching) flow ； When the velocity of a fluid particle changes only in a direction perpendicular to the flow direction, it is called shear flow.
When the velocity of a fluid particle changes only in a direction consistent with the flow direction, it is referred to as (stretching) flow ； When the velocity of a fluid particle changes only in a direction perpendicular to the flow direction, it is called (shear) flow.
The first fills with laminar flow, the second with turbulent flow
When the velocity of a fluid particle changes only in a direction perpendicular to the flow direction, it is called shear flow.
1. Those with the same direction are: tensile flow. 2. Those with a perpendicular direction are: shear flow
The change in the velocity of a fluid particle only in the direction consistent with the flow direction is referred to as (stretching) flow； Flow in which the velocity of fluid particles changes only in a direction perpendicular to the flow direction is called (shear) flow.
