Pressure Drop

Mentor Graphics concurrent CFD tool FloEFD is the perfect software tool for simulating and analyzing pressure in an engineer’s 3D MCAD design.

Use your existing design tools

Mentor Graphics concurrent CFD software, has been specifically designed for the Design Engineer. It enables a user to analyze pressure and a range of pressure-related parameters using ‘what-if’ scenarios, the engineer is then able to quickly modify and optimize their designs CAD geometry within their native CAD system, analyzing in detail why the flow of gas or liquid may be higher or lower than that allowed for by the technical specification.

Reduce design efforts

In the past, this level of product/component optimization would have required an Engineer with many years of experience and the manufacture of countless physical prototypes to approach the level of success concurrent FloEFD allows.

Decrease time-to-market

Using concurrent FloEFD in the early stages of the design process helps eliminate the need for multiple prototypes; it helps increase reliability, saves time, saves money and gets your product to market faster.

Device Flow Coefficient Determination

Device Flow Coefficient Determination (cv/kv/Qn)

simulate pressure drop across the device

Flow coefficients describe the efficiency of a hydraulic or pneumatic device. It is the relationship between the pressure drop across the device and the corresponding flow rate. Concurrent FloEFD is the ideal analysis tool for calculating flow coefficients for hydraulic and pneumatic devices. Both easy to use and fast, it allows an engineer to quickly determine the optimum design for his/her product specification.

simulate pressure drop with FloEFD

Preparing a model for analysis is very easy with FloEFD. Unlike traditional CFD programs that require a user to create additional solid parts to represent the fluid (empty) regions, FloEFD automatically differentiates between the CAD geometry for internal and external flows and automatically represents the fluid domain area.

Jet Pump Dimensioning

Jet Pump Dimensioning

simulate pressure drop in jet pumps

Eductor-jet pumps or aspirators are frequently used to pump combustible liquids or for applications where complex moving parts are not desired, e.g. to pump debris, to ensure high reliability, etc. FloEFD can be efficiently applied to test these jet pump designs, enabling an engineer to quickly determine their efficiency and optimize their performance.

Optimizing filter efficiency is often a major objective when improving the overall energy efficiency of many types of device. FloEFD includes as standard, specific functionality to address these requirements. These include: multiple filter modeling options for cost-effective simulations, the handling of complex filter housings and comprehensive 3D visualization functions that help an engineer understand just what is happening within the product.

Preparing a model for analysis is very easy with FloEFD. Unlike traditional CFD programs that require users to create additional solid parts to represent the fluid (empty) regions, FloEFD automatically differentiates between the CAD geometry for internal and external flows and automatically creates the fluid domain. As a result, engineers are able to concentrate on their project as opposed to creating extra geometry in their CAD system, saving them time, money and effort.

Pressure Drop Examples:Pump Efficiency

Pump Efficiency

Improving pump efficiency is always high on the list for the development of the overall efficiency of pump design. Pump efficiency is the ratio between the power imparted to the fluid by the pump and the power consumed by the pump itself to run. FloEFD can be used to determine pump efficiency and to optimize the design of pump components such as housing design, impeller, inlet and outlet sections, etc. for improved efficiency.

Concurrent FloEFD's sophisticated multiple rotating reference frame capability combined with easy handling of complex native CAD model data allow cost-effective simulations of pumps of various designs.

Fan Characterization

Fan Characterization

Improving the efficiency of a fan can be a major challenge for the design engineer. The objective is to not only reduce the fan's energy consumption, but to improve mechanical reliability and decrease noise levels. Fan operation is characterized by fan curves as relationship of airflow vs. static pressure.

Thanks to sophisticated multiple reference frame models, Concurrent CFD can be used to simulate these fan characteristics easily. FloEFD allows an engineer to study the flow and pressure fields surrounding a fan unit in detail, not only identifying potential areas for improvement in energy efficiency, but also identifying potential sources of unwanted noise and other related effects.
