Fluid Mechanics and Aerodynamics Thermodynamics and Thermotechnics Process Control



Self-contained and mobile unit for demonstration of the properties of fluids and hydrostatics. Structure in anodized aluminium, assembled on wheels with a panel (painted steel) at the top (front panel). Process diagram in the front panel. Tank where water is stored, in the lower part of the bench. Methacrylate tank at the upper part of the bench. Plastic deposit. Thermometer. 4 Ubbelhode capillary viscosimeters of 0.6-3 cp, 2-10 cp, 10-50 cp and 60- 300 cp. 3 Graduated cylinders. Set of glass elements.

Elements set for demonstration of free surface in static conditions (3 elements). Bourdon manometers calibration. Manometer range: 0-2.5 bar. Manometers (range: 0-500mm). Module to determine the Metacentric Height (FME11): Maximum angle: +/-13. Corresponding lineal dimension: +/- 90 mm. Dimension of the float: L=353mm, W=204mm, total H=475mm. Module for studying the Hydrostatic Pressure (FME08): Fluid Level Meter (hook and point gauge) and Flow over Weirs (FME02): Module for studying Archimedes principle (lever balance with displacement vessel, bucket and cylinder). Set of weights (5, 10, 50, 100, 400, 1000, 2000, 5000 gr.).

One air pump and 2 water pumps. Universal hydrometer (0-70 Baumé , 0.700 - 2.000 Sp/gr). Stop clock. Two 600 ml beakers. Spare parts for the viscosimeter elements. Valves. Manuals: This unit is supplied with 8 manuals. Dimensions (approx.): 1500 x 800 x 1900 mm. Weight: 200 Kg.  The Laminar Flow Visualization Unit (LFA) allows a complete study of the twodimensional problems associated with the laminar flow by means of the visualization of the different models of flow that can be visualized with the help of an efficient system of injection of coloured liquid.

It is equipped with wheels for mobility and with brake to immobilize the unit during the practices. Anodized aluminium and steel structure. Process diagram in the front panel with similar distribution to the elements in the real unit. Laminar flow visualisation table. Flow visualisation area. 8 sources and 8 drains. Control valves of the drains and sources. Input control valves. Tank of ink. Manifold of ink. Draining valve. Tank at the input and output of the work section. Grid to facilitate the visualisation of the lines of flow. The top glass sheet of the visualisation area has handles to be able to lift it with easiness for its correct operation or to install the different hydrodynamic models.

The central drain of the inferior badge, placed in the visualisation area, has a double-shape, that is to say, two orifices in vicinity. The control systems allow that every, or some, of the drains and sources are fed at the same time. Coloured liquid injection system, for a better visualization of the lines of flow: 19 needles, placed among the glass sheets at the input. Through each needle an appropriate quantity of colouring is injected and the direction is visualized with clarity. It includes a set of hydrodynamic models formed by: 3 circular models: 40, 60 and 80 mm diameter. 3 square models: 40, 60 and 80 mm of length.

1 wingshape model. Manuals: This unit is supplied with 8 manuals Dimensions (approx.): 1600 x 1000 x 1250 mm. Weight: 60 Kg. Dimensions of the working area: 600 x 900 mm. With process diagram in the front panel. The unit control elements are permanently computer controlled. Simultaneous visualization in the computer of all parameters involved in the process. Calibration of all sensors involved in the process. Real time curves representation. All the actuators’ values can be changed at any time from the keyboard. Shield and filtered signals to avoid external interferences.
