Shift Your Machine Performance into High GearDesigning fluid
machines poses many challenges. Especially in recent years, the
demand for equipment miniaturization, better performance output,
improved efficiency, and noise reduction has increased.
Manufacturers today face the pressure to deliver well-balanced
products in a short amount of time (as shown in Q1 below). To
satisfy customer needs and continually provide quality products, it
is crucial for engineers to understand the fundamental physics
behind design.
Possible Design Common approaches to design solutions are shown
below. Each has advantages and disadvantages.
Modify machine based on past experience and know-how
Leverage design experts. Relatively fast turnaround. Incremental
design approach.
Advantages Disadvantages
Modification of real hardware
Analysis
Trial and experiments
High risk as operability envelope becomes smaller. Can only
achieve locally optimized solutions.
High confidence about how actual product will perform in the
field.
Time consuming and costly to build hardware and run tests.
Incremental design improvements.
Flow visualization enables improved understanding of physics and
results in better design proposals. Evaluate many design options.
Assess new concepts.
Analysis results must first be validated using available test
data.
Use test data to drive design modifications
Use CAE software to evaluate new design solutions

Applying CAE software helps design engineers reach a
breakthrough by visualizing the invisible. As shown in the table
below, it can be a solution to many commonly occurring
problems.
CAE software is most frequently used during the preliminary and
detailed design stages.

CFD Users Say...CFD is effective to explain product performance
to non-specialists by visualizing the invisible. It helps our
engineers make decisions and evaluate designs in a short amount of
time. This ultimately shortens development time, especially when we
use CFD in the early design process.
SC/Tetra enabled us to visualize the phenomena occurring within
our designs, which helped us logically convince our managers and
customers of the product capability with visible evidence. We are
grateful that Software Cradle provided prompt and exceptional
support for our engineers to process tasks efficiently.

Targets
Reduce design cycle time Analyze simple design concepts under
different operating conditions. Observe how design changes affect
the results.
Reduce costs
Design highly competitive products
Facilitate understanding of numerical information
Address on-site issues and concerns
Run a number of tests and evaluate more design options.
Visually assess both local and overall performance. Numerically
calculate performance values.
Use still images, animation, and representation on 3D viewers to
explain the numerical results.
Use simulation to analyze the problem and evaluate
solutions.
Evaluate design directions, examine product performance, and
address problem areas early in process.
Reduce cost by minimizing the amount of tests and
prototypes.
Rank and select best performing concepts. Develop plans for
product upgrades and improvements.
Help non-specialists understand the logic by visual graphics and
animations.
Identify problems, compare possible solutions and solve the
issues quickly.
