  1. In-Cyclinder Flow Simulation For Single Cyclinder Diesel Engine
  • Summary:--
    • ANSYS IC-ENGINE tool was used to study the in-cylinder flow characteristic which uses ANSYS FLUENT as solver.
    • IC-Engine tool is robust tool dedicated for IC engines. It is used for modeling and solving steady flow, transient flow, combustion characteristics and full cycle simulation.
    • A transient simulation was performed to study the air flow characteristics during intake stroke and compression stroke.
    • Various flow parameters like swirl ratio, tumble ratio, cross-tumble ratio, turbulence kinetic energy and turbulence dissipation were plotted with crank angle degrees. 
    • A comparison for flow parameters was performed after performing iterations in the design of intake port.
    • The simulation was performed on an 8 core Linux based compute node which enhanced the computational performance.
  • Advantages:--
    • Flow simulation provides an early understanding of the in-cylinder flow in the design stage
    • Effect of geometry modification on flow parameters can be studied qualitatively and quantitatively and decisions on the final design becomes easier after considering all results.
    • An effective technique (in terms of time and cost), for a new prototype engine or for modifying a baseline engine
    2. Static Structural Analysis (Linear)
  • Summary:--
    • ANSYS MECHANICAL was used to perform the static structural analysis of an automotive component.
    • The objective was to analyze the component for the static loading conditions.
    • For first case, a pre-load to the bolt (flexible body) was provided as mechanical loading condition and for second case moment was applied on the bolt (rigid body).
    • Stress, deformation and strain results were studied and convergence technique was used to obtain a mesh independent solution
  • Advantages:--
    • Static structural analysis provides the basic response of the system due to static loading. This would immensely help in the early design stage.
    • Results can be used for geometry modifications if required and can be further analyzed for dynamic loading.
    • Results can be obtained within a short period of time
    3. Thermal Coupled Static Structural Analysis (Linear)
 
  • Summary:--
    • ANSYS MECHANICAL was used to perform the thermal coupled static structural analysis of an automotive component. 
    • The objective was to analyze the component for thermal as well as structural loading
    • A constant temperature was assigned as thermal load and pressure was applied as mechanical load.
    • Stress, Deformation, thermal strain results were studied and convergence technique was used to obtain a mesh independent solution
  • Advantages:--
    • If the environment of the component involves thermal conditions like temperature, this type of analysis is suitable
    • A transient thermal run can also be used to obtain the temperature values over the system and then a structural load can be applied to study the coupled effect
