Product Optimization

“If you keep your eye on the profit, you’re going to skimp on the product. But if you focus on making really great products, then the profits will follow.” Steve Jobs.

Product Optimization

This type of study is especially beneficial for those manufacturers intending to improve the design of already operational equipment. By dint of the parameterization of some geometric characteristics previously defined in cooperation with the client, it is possible to carry out a sweep that allows knowing which are the most influential, managing to redefine them to obtain the optimal design.

Pump

Parametric optimization of a Centrifugal Pump

$

Project

This project seeks to modify an already operational centrifugal pump to enable it to work at a greater range of heights. The aim is to see if a new, more efficient design can be reached —one that meets the new requirements— by modifying only some of the elements of the current equipment. For this purpose, the geometry of the model is parameterized in order to carry out different simulations varying the elements previously defined with the customer.

$

Parameters

In this case, the number of blades of the equipment and their width are defined as study parameters. However, the parametric models developed by DPO FLUID allow studying any geometric characteristic.

Results

Centrifugal Pump

CFD simulations show that in a range of blade number variation from 7 to 12, the 9 blade pump achieves the highest efficiency values while meeting the required head-flow requirements. Once the number of blades has been defined, it is evaluated whether increasing the width of the blades can further optimize the new design. However, it is the initial width that allows reaching a greater efficiency in the required design area.

Silencer

Parametric optimization of Engine Silencer 

$

Project

This study optimizes a base design of a reactive-dissipative industrial engine silencer. To this end, alternative designs to the original are evaluated for the expansion chambers and the reactive chamber.

$

Rediseñaos

In the case of the expansion chambers, it can be seen that greater attenuation is achieved by extending the inlet and outlet pipes into the equipment.

As for the reactive chamber, a redesign is proposed replacing the circular crowns with tubes, smooth or perforated. 

$

Optimized model

This redesign maintains the total area of passage of the combustion gases so as not to vary the pressure drop with respect to the original design. It is concluded that the optimal design is the one that uses perforated tubes.

Results

Engine Silencer

The results show how the transmission losses of the silencer are increased by 20.2% using the pipe extensions in the expansion chambers and the new design of the reaction chamber with perforated pipes. The new design is proven to respect the pressure drop restriction.
