Learn how PNR can effectively optimize nozzle performance with Computational Fluid Dynamics software

At PNR we have been working for a long time to be at the forefront in the production but also in the design and optimization of our products. For this reason, we have equipped ourselves with a software for computational fluid dynamics.

What is computational fluid dynamics?

Computational fluid dynamics, commonly referred to as the English acronym CFD Computational Fluid Dynamics, identifies the numerical technique that allows the study of fluid mechanics through the use of computers.

What are the fields of application of CFD in PNR?

Thermo-Fluid Dynamics Simulations
Optimisation of products

What are the advantages of CFD for PNR?

CFD analyses allow us to predict in advance the performance of a given product even before it is carried out, studying it as if it were already operating in the laboratory. This results in considerable savings in terms of time and resources.

THERMO-FLUID-DYNAMIC SIMULATIONS

The Thermo-Fluid Dynamics simulation allows us to investigate and predict the trend of thermal and fluid dynamics variables. Specifically we can analyze:

Analysis of static and dynamic cooling;
Sizing systems and coverage analysis;
Temperature distribution and thermal analysis.

We have developed a dynamic proprietary thermal analysis model for the study of continuous cooling in extrusion and in the main metallurgical processes.

Thanks to the CFD software, we have obtained a dynamic simulation of the washing heads.

In detail, we can make:

Analysis of the actual coverage and the action of wall washing;
Simulation of viscous fluids / non-newtonians;
Prediction of actual rotational speed;
Analysis of fluid forces – moving walls.

OPTIMISATION OF PRODUCTS

This CFD software is a powerful research and development tool that allows us to test different solutions for the optimization of our products in a very short time compared to traditional prototyping.

In detail we can obtain:

Assistance with production;
Optimization of performance;
Tuning and analysis of the influence of geometric parameters;
Search for new solutions;
Reverse Engineering.
