Spray Combustion

​

Introduction

• Modeling of spray combustion is vital for design of various combustion systems 

• In particular, internal combustion engines and gas turbines

• Complex physical dynamics:

  • Droplet evaporation​ and atomization

  • Mass, momentum, and energy two-way coupling with the flow

​

Research Details

• Liquid spray droplets are modeled via a Lagrangian-Eulerian approach 

• Specially designed two-way coupling for fast compressible flows

• Development of an improved stochastic secondary atomization model

• Droplet breakup and evaporation processes are fully conservative
