| Abstract: | Development of water resources plays a very important
role in the overall development of any country. Besides this, proper management
and utilisation of water resources also help in flood control, water supply for
drinking, industry, thermal and nuclear power plants, irrigation, hydro power
generation, etc. For the development and management of water resources, the
design / construction of various hydraulic structures and installation of
related machines are an important task. Theoretical and empirical methods of
analysis and calculations do not
provide adequate solution to various hydraulic problems
due to complexity of boundary, fluid and flow characteristics. The engineers
involved in the design of hydraulic structures are always keen to know the
performance of such structures after its construction and commissioning of the
project. Therefore, there is no-option except to study the hydraulic phenomenon
on a physical model. The validity of model predictions
greatly depend upon the judicious simulation of the
parameters, affecting the flow besides boundary characteristics. The studies of
different parameters such as velocity distribution, pressure, behaviour of
flow, efficacy of design of hydraulic structures / machines have been mainly
carried out in the model studies to allow flow of water through a model constructed
at a smaller / bigger size than that of prototype. Hydraulic
model studies are conducted mainly on the basis of
Froude's law of similarity, Reynold's law of similarity, etc. by physical,
electronic/electrical and mathematical / numerical modeling. A number of model
studies have been carried out at Hydraulic Research Station, Bahadarabad of IRI
Roorkee, a brief account of some important studies has been presented in the
article besides description of its basic principle and concept of the method of
the model studies. |
