Oil Tank Analysis for Formula Student Car: Heat Transfer Calculations

Click For Summary
SUMMARY

The discussion focuses on designing an oil tank for a Formula Student car, specifically analyzing the existing oil tank from the Aprilia SXV 550 engine. Key calculations include determining heat loss through conduction, convection, and radiation, as well as calculating inlet and outlet temperatures of the lubricating oil. Essential formulas for heat transfer, such as Fourier's Law and Newton's Law of Cooling, are recommended for accurate calculations. The discussion also emphasizes the importance of using a suitable Finite Element Analysis (FEA) package to validate results.

PREREQUISITES
  • Understanding of heat transfer principles, including conduction, convection, and radiation
  • Familiarity with Fourier's Law and Newton's Law of Cooling
  • Knowledge of Finite Element Analysis (FEA) tools
  • Basic thermodynamics, including heat capacity and flow rate calculations
NEXT STEPS
  • Research suitable FEA packages for thermal analysis, such as ANSYS or COMSOL Multiphysics
  • Learn how to calculate heat transfer using Fourier's Law and Newton's Law of Cooling
  • Investigate methods for measuring oil flow rate and temperature in automotive applications
  • Explore design considerations for optimizing oil tank size and weight while maintaining heat dissipation
USEFUL FOR

Mechanical engineers, automotive designers, and students involved in Formula Student projects who are focused on thermal management and heat transfer calculations in engine oil systems.

Hi Guys,
This is for my university project.I need to design a oil tank for the formula student car.The first stage is the analysis of the existing stock oil tank (Aprilia SXV 550 is the engine).I need to find out the heat lost/transferred from the of the existing oil tank.How can I calculate the inlet and exit temperature of the Lubricating oil(passing through the tank).
I need to do the corresponding heat loss calculations happening through the oil tank.
I will be considering all the modes of heat transfer
Conduction,Convection and Radiation.
Please tell me How can I justify that a particular value of heat is lost from the oil tank with the help of calculations.And what formulas of heat transfer should i use (Fourier's,Newton's Law of cooling ...?)
What is the suitable FEA package that can be used for justifying my results...?

First I would measure or look up the existing steady state (eg end of race) values for:

Inlet and outlet oil temperature
Oil Flow rate
Heat Capacity of the oil

eg measure the first two and look up the last.

Then you can easily work out how much power is being dissipated by the existing tank/oil cooler.

Presumably the new lank has to be smaller, lighter and dissipate the same or more power.
