Heat Transfer Calc for Oil Tank in Formula Student Car

Click For Summary

Discussion Overview

The discussion revolves around the heat transfer calculations for an oil tank in a Formula Student car, specifically analyzing the existing oil tank from an Aprilia SXV 550 engine. Participants explore methods to calculate heat loss and temperature variations of lubricating oil as it passes through the tank, considering various modes of heat transfer including conduction, convection, and radiation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant requests guidance on calculating inlet and exit temperatures of lubricating oil and the corresponding heat loss through the oil tank.
  • Another participant suggests that knowing the temperature and flow rate of the oil entering the oil pan is essential for calculating convective heat loss.
  • It is proposed that radiation heat loss may be negligible in this scenario.
  • A participant inquires about measuring the necessary temperature and flow rate values for accurate calculations.
  • One participant questions the necessity of calculating heat flow out of the oil pan, suggesting the use of an oil cooler instead.

Areas of Agreement / Disagreement

Participants express varying opinions on the significance of radiation heat loss and the necessity of measuring specific parameters, indicating that multiple views remain on the best approach to the problem.

Contextual Notes

Participants have not reached a consensus on the specific formulas to use for heat transfer calculations or the relevance of radiation in this context. There are also unresolved questions regarding measurement techniques for the required parameters.

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...?

You're going to need to know what the temperature and flow rate of the oil is coming into the oil pan, or maybe an average tempertuare of oil in the pan. Then, given a flow of air over the pan you can calculate the convective coeffcient and the heat loss through convection.

My guess is you'll be able to ignore radiation heat loss in this case.
 


hello
you said student Formula car...if this is right...you have big task ahead of you..can you post photos of engine and the FC

Thank you Mech_Engineer...
How should I measure these values..Any Ideas or suggestions...?
It will be helpful for me.
 


Well, you could start with the obvious- an http://www.summitracing.com/parts/ATM-3348-M/ ...

Why do you care about the heat flow out of an oil pan though, why not use an oil cooler?
