Dynamic similarity is satisfied by looking at the force distribution at corresponding locations in the flow. The forces must have the same direction and their magnitudes must be constant multiples of each other.
Conditions: Presented after geometric and kinematic similarity have been established.; Concerns force distribution at corresponding locations in the flow.; Force directions must match.; Force magnitudes must be constant multiples of one another.

Similitude and modeling serve as a validation framework for analytical or computational flow solutions. The speaker explains that obtaining a result is not enough; experiments are needed to assess whether the results are valid.
Conditions: Used when assessing validity of analytical or computational solutions; Experimental confirmation is required; Results need only be similar, not identical

Kinematic similarity requires that velocities and accelerations at corresponding points in the two flows have the same direction and their magnitudes must be constant multiples of one another. It is the next requirement after geometric similarity.
Conditions: Requires geometric similarity as a prior condition.; Concerns corresponding points in the two flows.; Velocity and acceleration directions must match.; Velocity and acceleration magnitudes must be constant multiples of one another.

Geometric similarity requires that the ratios of corresponding linear dimensions between the model and prototype are equal. For the two rectangular-box examples shown, the condition is expressed as bB=hH=wW.
Conditions: The compared objects must have corresponding linear dimensions.; Each ratio pairs a prototype length with the matching model length.; Applies to corresponding linear dimensions of two objects or domains.
