Blocked vessels

High-fidelity modelling of blood flow in stenosed arteries to predict turbulence, cavitation, and plaque instability mechanisms associated with cardiovascular events such as myocardial infarction

Technical capabilities in MPflow

  • Multiphase CFD modelling of blood flow in stenosed arteries
  • Resolution of pressure drops and recovery across constrictions
  • Cavitation modelling including bubble inception and collapse in vascular flows
  • Prediction of shear stress distributions linked to plaque formation and rupture
  • Support for patient-specific geometries and varying stenosis severity (50–75%+)
  • Transient simulations capturing pulsatile blood flow conditions

Our CFD approach

  • High-resolution simulation of flow through coronary artery stenosis
  • Identification of low-pressure regions triggering cavitation
  • Coupled analysis of turbulence, shear layers, and recirculation zones
  • Investigation of plaque stability under varying flow conditions
  • Modelling of pressure fluctuations driving bubble dynamics and collapse
  • Detailed insight into flow-induced mechanisms leading to thrombotic events

Physics-based ML acceleration
