Complete similarity (Similitude) is not always possible because complete modeling is not always possible. Geometric Similarity is easy. We just need the model to be a good scale representation. Kinematic Similarity is harder because we need the test conditions to mirror expected system conditions.
WebApr 29, 2024 · The necessity for geometric similarity is the most obvious. Kinematic similarity in fluid mechanics is often referred to as the similarity of streamline patterns. Dynamic similarity requires that forces in full and model scale have the same direction and the ratio of magnitudes full scale to model scale is constant.
WebDec 15, 2024 · Dimensional analysis is the basis for the determination of laws that allow the experimental results obtained on a model to be transposed to the fluid system at full scale (a prototype).
