Mixing Processes

Concurrent FloEFD allows any design engineer with CAD experience to virtually understand outflow streams.

Over-coming mixing challenges

The mixing of fluids or gases can pose more questions than answers for a Design Team. Fluids and gases combine through a complex series of physical processes that may include multiple species transport, conjugated heat transfer between fluids and surrounding solid materials, multiple inlets and/or outlets with various material concentrations, etc.

Empowering design engineers

It’s fairly straightforward to specify the inflow streams, but the outflow(s) depend on what happens within the mixing vessel itself. By using concurrent CFD software FloEFD, any design engineer with CAD experience can perform these tasks ‘virtually’, allowing them to investigate and better understand the reason for a particular concentration distribution by simulating the internal flow in 3 dimensions.

Decrease time-to-market

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

Success Stories

Nozzle Design

Simulating the mixing processes within a spray nozzle

Simulating the mixing process within a spray nozzle is characterized by the requirement to handle very complex geometric flows while delivering very accurate results for the computed flow and pressure parameters. Yet this is fundamental to predicting the concentration distributions of the various species to be mixed within a nozzle.

Concurrent FloEFD is the perfect CFD tool for this task because it uses the users’ native CAD geometry directly, automatically creating high-quality computational meshed grids for accurate reliable results. FloEFD's suite of physical models allows a user to mix up to 10 different species at the same time, with each fluid having its own set of physical parameters such as viscosity, density, thermal properties, etc, attributed to it.

Rubber Co-Extrusion

mixing processes in simulation of rubber co-extrusion

The simulation of rubber co-extrusion is a major challenge to engineers due to the complex nature of the fluids and their interaction along the materials interfaces. Concurrent FloEFD includes a built-in set of processes related to rubber co-extrusion, these include visualization of the distributed various rubber types across the extrusion die outlet, simulation of the three-dimensional co-extrusion process within the die, the residence time distribution within the die and much more.

All this can be analyzed based on a users CAD model of the die without expensive physical die modifications and experiments on the extrusion process line. To accomplish this, Concurrent FloEFD provides automatic grid generation of the extremely complex in-die flow domain from the designers MCAD geometry, along with sophisticated models to simulate the flow behavior of the rubber liquids and the interaction of the rubber with the die walls.

Cleansing Processes

Stringent hygiene requirements can be the key performance parameters for engineers who design equipment used for cleaning or sterilization purposes, equipment such as dish washers. These types of equipment often require the mixing of agent liquids with water or other carrier liquids in a precisely defined way and then to deliver these specified concentrations to specific parts of the equipment to ensure that the cleansing process is fulfilled.

FloEFD enables an engineer to better understand the flow and liquid mixing-related aspects of a design upfront, at the early stages of their CAD digital geometry models. It allows them to predict and verify the mixing quality and the resulting cleansing effect and to draw detailed conclusions for design improvements prior to prototyping and manufacture.

Bathroom Mixers

High-end bathroom faucets (mixer taps) with innovative design functions and quality requirements can challenge an engineer to provide perfect mixing results and to provide exactly the required temperature under all flow rate conditions, without start-up issues, noise issues, pressure drop issues, etc, etc.

Mentor Graphics concurrent CFD tool FloEFD, is able to produce highly detailed simulations of the hot and cold water supplies mixing within the design. Because the software is embedded, detailed analysis on the users CAD geometry enables FloEFD to predict the temperature profile of the products surfaces easily, quickly.

Furnaces and Combustion

Furnaces and Combustion

mixing processes in furnaces and combustion

The challenge to build energy-efficient furnaces, require specific flow patterns to effectively mix patterns of various combustible materials. Concurrent FloEFD's built-in analysis of flow and mixing capabilities, together with its generation of the computational mesh based on native CAD geometry data, can help an engineer produce a large number of variations of furnace designs and their inflow conditions to help identify the best possible design variant.

Because of FloEFD’s quick upfront analysis process in the design workflow, design engineers can now investigate various design alternatives using ‘what-if’ scenarios. This helps the engineer to better understand the reasons for a particular mixture distribution, and why the results may be higher or lower than allowed by the technical specification.
