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

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.
