Tunnels have been utilized in one form or another to explore fluid mechanics and
aerodynamic phenomena since the days of Leonardo da Vinci. Only in recent years,
however, have Water Tunnels been recognized as highly useful facilities for
critical evaluation of complex flow fields on many modern vehicles such as high
particular, Water Tunnels have filled a unique role as research facilities for
understanding the complex flows dominated by vortices and vortex interactions.
Flow visualization in Water Tunnels provides an excellent means for detailed
observation of the flow around a wide variety of configurations. Perhaps the
most valuable feature is the ability to
simultaneously measure forces and observe the flow
visualization. The free stream
flow and the flow field dynamics are low-speed, allowing real time visual
assessment of the flow patterns using a number of techniques, including dye flow
through ports in the model, hydrogen bubble generation from strategic locations
on the model, or laser light sheet illumination.
Between Water Tunnel and Wind Tunnel Flows
of flow visualization in a water and
wind tunnel experiment on a common model show nearly identical vortex flow
patterns, clearly illustrating that Water Tunnel observations have direct
application to aerodynamics.
Hills Research Corporation offers three Water Tunnel models in its Eidetics®
product line. The water tunnel kits include a detailed set
of assembly instructions and a videotape showing every step of the assembly

2436 has a 24x36x72 inch test section and is available as a fully
assembled and installed system or as a kit.
|Model 1520 has a 15x20x60 inch test
section and is available as either an assembled and installed system or as
0710 has a 7x10x18 inch test section. It was specifically designed as
an affordable teaching tool for High Schools and Universities while still
retaining many of the world-class features of RHRC's larger research
If the standard water tunnel configurations don't
meet your requirements, RHRC can also produce custom water tunnels to meet your specifications
of the important available features of the Water Tunnels include:
speed, nominal maximum of 1 ft/sec (5 in/s for Model 0710)
glass-walled test section
plane viewing window
3-axis dynamic model support
3 or 6-color
pressurized dye system
force/moment balance (optional)
offers a series of prepared
experiments that demonstrate basic fluid dynamic concepts. Each experiment comes with the necessary model,
installation instructions, and an explanation of the
underlying fluid dynamic theory including the important
items to observe during the experiment. In addition
to these experiments, RHRC also produces custom models
to the customer's specifications.
