Model Test Entity

  • Claus WeilandEmail author


When humans have built large technical devices like bridges, ships, buildings, embankment dams, airplanes, space planes, reactors for chemical purposes, hydraulic engines (pumps, compressors, turbines) etc. there was a need to fabricate geometrically similar models of these devices in order to investigate and test their physical behavior in ground based test facilities. The main question from the physical point of view in this regard is under what conditions are the experimental test results, received with geometrically similar models in test facilities, transferable to the situation of the original devices? We define the three similarity rules, which must be kept for a suitable testing of the physics of originals in test facilities, [1, 2].
