(engineering)
A likeness or resemblance; for example, the scale-up of a chemical process from a laboratory or pilot-plant scale to a commercial scale.
(physics)
The use in scientific studies and engineering designs of the corresponding behavior between large and small objects or systems which are of similar nature and, more precisely, have geometrical, kinematic, and dynamical similarity.

Similitude theory has been well developed and widely used in the field of fluid dynamic.
And yet he maintains the impossibility of similitude: "no Man is so different from another as the Same man is from himself" (239-40)--an opinion that is itself readapted from Montaigne's "De l'inconstance" (II.
If he "took" photographs, he also described the daguerreotype as "a chemical and physical process that gives Nature the power to reproduce herself." In addition, he is perhaps the most analogical of the early pioneers of photography: His graphic oeuvre, punctuated by repetition--by multiples and variants of single motifs--is an exemplar of similitude.
Background: Homeopathy is based on treatment by similitude (Tike cures like') administering to sick individuals substances that cause similar symptoms in healthy individuals, employing the secondary and paradoxical action of the organism as therapeutic response.
In similitude, the World Expo, if hosted by Dubai would also add a fillip to it.
A model is said to have similitude with the real application if the two applications share geometric similarity, kinematic similarity and dynamic similarity, as follows: 1) geometric similarity--the engineered model is the same shape as the application, but usually scaled; 2) kinematic similarity--fluid flow of both the model and real application must undergo similar time rates of change motions--(fluid streamlines are similar); and 3) dynamic similarity--ratios of all forces acting on corresponding fluid particles and boundary surfaces in the two systems are constant.
"The similitude of the two parties is as the blind and the deaf and the seer and the hearer.
