Motivation & Objectives

  -The motivation is that little attention was paid to directly comparing the consistency of Eulerian & Lagrangian approach. 

-The main objective is to propose an efficient Eulerian method to obtain statistical flow characteristics based on individual particles.

           : To verify EPIs(Eulerian Particle-property Indices) with equivalent LPIs(Lagrangian Particle-property Indices)

Flow fields

 -Various  EPIs(Eulerian Particle-property Indices) can be derived for particle-based properties like residence time, travel distance, enthalpy, accumulated centrifugal force, accumulated radial force

 -  EPIs and LPIs are compared at the swirling pipe,  IC engines and cooling tower.
