NUMERICAL MODEL BASED ON A BERNOULLI INTEGRAL EXTENSION FOR PRESSURE ANALYZE ON A MILLIMETER DEVICE IN A TURBULENT FLOW

Gheorghe NISTOR, Adrian ZAFIU, Dinel POPA

Abstract


There massive calculus resources are needed for computing a RANS fluid motion and a piezoelectric model, as we already noticed in our previous models      . The matched and verified hypothesis about the device response and qualitative behavior make a new approach to be necessary. Therefore, some theoretical and field observations on PDEs together with the applied genetically algorithms immerge for the problem’s convergent solution. The aim of the paper is to validate a model computed with a fluid pressure depending on fluid speed and device' body dimensions for optimal electric response.

Key words: turbulence flow, Bernoulli integration extension, pressure analyze
