Oil Tank Analysis for Formula Student Car: Heat Transfer Calculations

AI Thread Summary
The discussion focuses on designing an oil tank for a Formula Student car, specifically analyzing the heat transfer of an existing oil tank from an Aprilia SXV 550 engine. Key calculations include determining the inlet and outlet temperatures of the lubricating oil, as well as the heat loss through conduction, convection, and radiation. Participants suggest measuring steady-state values such as oil temperature, flow rate, and heat capacity to calculate the power dissipated by the current tank. The need for the new tank to be smaller, lighter, and equally effective in heat dissipation is emphasized. Appropriate heat transfer formulas and FEA packages for validation are also sought.

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.

Thanks CWatters...
 
Been around 40 years since I took basic physics in college and while I remember doing some examples of insulation values / energy conduction, I doubt I could to the math now even if I could find the formulas. I have some some corrugated plastic sheet (think of the plastic signs you see on the side of the road) that is used in bee hives. Also have some used in a green house though a bit different in dimensions than this example but the general approach should still apply. Typically, both...
Problem: You’re an Uber driver with a Tesla Model 3. Today’s low: 30F, high: 65F. You want to reach a USD$ profit target in the least number of hours, but your choices could have added cost. Do you preheat the battery only when you are headed to the charging station (to increase the charging rate by warming the battery — however the battery might not be “warm enough” when your reach the charger and thus slower charging rates), or do you always “navigate to the charger” the entire day (which...
Thread 'Is Callen right in claiming dQ=TdS for all quasi-static processes?'
Hello! I am currently reading the second edition of Callen's Thermodynamics and an Introduction to Thermostatistics, and I have a question regarding Callen's definition of quasi-static. On page 96, Callen says: Another way of characterizing Callen's definition is that a process is quasi-static if it traces out a continuous curve in the system's configuration space. So far it's all well and good. A little later, Callen claims that the identification of $$TdS$$ as the heat transfer is only...
