Classification of models
The
classifications of models are
i. Undistorted models
ii. Distorted models
Undistorted model
If
the scale ratio for the linear dimensions of the model and prototype is same,
then the model is said to be undistorted model.
Distorted model
A
distorted model is said to be a distorted model only when it is not
geometrically similar to prototype.
Advantages of distorted models.
The
advantages of distorted models are,
1. The
vertical dimensions of the model can be measured accurately.
2. The
cost of model can be reduced.
3. Turbulent flow in the model can be maintained.
