The Rolling Hills Research Corporation Model 0710 University Desktop Water Tunnel
is the latest addition to RHRC's Eidetics® line of water tunnel research
products. RHRC water tunnels have been
produced since 1985, providing many satisfied
customers with excellent research and educational facilities. While retaining many of the
world-class features of RHRC's larger research water tunnels, the new Model
0710 is designed specifically to be an affordable teaching tool for High
Schools and Universities. The new 2nd generation design includes
a 1-piece powder coated steel frame, just like our larger research water
tunnels. RHRC has developed a series of prepared
experiments that illustrate fundamental fluid dynamic principles.
Inexpensive
plastic models can easily be fabricated or assembled from off-the-shelf kits.
Flat plates, cylinders, spheres, aircraft and automotive models can all be
used very effectively to demonstrate fluid dynamic phenomenon, from simple to
very complex.
The new, second generation water tunnel features a new flow conditioner
design that allows the honeycomb to be rotated to clear bubbles that can
distort the flow, assuring excellent flow quality in the test section.
 The
Model 0710 offers views of the test section through a downstream and two
side windows, all made of tempered glass. Glass is superior for use
with PIV
or LDV systems. Flow visualization
is provided by a three color, pressurized dye system with individual needle
valve controls. The Model 0710 features a variable speed
motor and a stainless steel pump, a turbulence reducing screen and honeycomb in the settling chamber, a
6:1 contraction ratio, and dual line return plumbing... just like RHRC's full size water tunnels, Models 1520 and 2436. The
University Desktop Water Tunnel is ideal for in-classroom demonstrations and
student research projects.
Optional
Speed Control
 The
basic Model 0710 comes as a single speed unit. An electronic speed control can
be added that greatly increases the flexibility of the system. Using the
electronic speed control, the speed in the test section can be varied from 0
to 5 inches per second. The only buttons that are normally used are the four
on the right-hand side: Start, Stop, Up Arrow and Down Arrow. The readout
displays the approximate speed in the test section, in inches per second. The
speed is increased by pressing the Up Arrow button and decreased by pressing
the Down Arrow button. The tunnel can be stopped at any time by simply
pressing the Stop button.
Calibration
RHRC
pre-calibrates each Model 0710 water tunnel before delivery to ensure that the
digital display displays the speed of the water in the test section, in inches
per second. The electronic controller has many additional programmable
features that are described in the manufacturer's Installation and Operation
Manual, which is included with the tunnel.
Summary of Unique Features
The Model 0710 University Desktop Water Tunnel
offers several important features that make it the best value for the money:
-
Tempered glass in the test section for high
quality photography and compatibility with laser systems such as
particle image velocimetry.
-
Great attention to flow conditioning has
resulted in low turbulence, uniform flow.
-
High resistance to corrosion through the use
of a stainless steel pump, baffles, and flow conditioners.
-
Comprehensive set of experiments are
available, including complete documentation, which can be cut-and-pasted
to easily create lesson plans.
