Engine Cooling System Efficiency 5.7 Hemi

While your buying time for your sock why can’t you offer answers for the questions I asked black betty ?

Sock puppet accounts unmasked by the way they write and post

Why don’t you criticize black betty ? Because that’s not the purpose of sock jerking? Black betty had a hard enough time to keep from contradicting themselves, it’s different when you try and form paragraphs for ideas ,
Is that you are dyslexic and in school you were bullied for it?

(not a personal attack is phrased in the form of a question)

or no one believed you had a problem ?
We all have our problems you think no one else has problems ? and that makes you angry?
Get over yourself already and stop trying to be the bully because even with your whole sock drawer you (vacuum) at it..

Seems quantity over quality is the strategy..

Interesting, my post wasn't even directed at you, yet you immediately get butt hurt and lash out. Rant and rave all you want, As Churchill said, "I would challenge you to a battle of wits, but I see you are unarmed".

And since you brought up dyslexia, you spelled can't wrong

You can try and tell yourself changing the flow rate doesn't effect heat transfer all you want but there's a whole lot of engineers that will tell you otherwise.

I provided a link from a cooling company that contradicts your statement. This is just one of many but I’m open to reading if you feel like providing actual data/information from credible sources.

 

[blackbetty14]

So in a helpful way you should be able to say if a restrictor plate will speed up coolant flow or slow it down.

When you mentioned laminar flow you use the phrase
“ film of fluid “ did you mean that to describe surface water tension ?

Cavitation would be caused by which… turbulence or rate of coolant flow ?

It does neither by itself that all depends on the hole size but more so affects the cooling regulation of the motor. It’s never closed so you have slow warm up and no bottom temp cutoff since there is nothing to shut flow off. A restrictor plate does nothing but restrict flow which has benefits like creating pressure inside the engine to help with cooling and raise the temperature before boiling can occur.

I’m not an engineer or an expert think of the cooling through a tube, the fluid on the edges that contacts the inside wall slows down while the inside flows faster acting like a film which insulates the inner fluid from cooling (Exhaust operates similarly) having the fluid turbulently flow through the tubes allows max cooling efficiency since more of the fluid touches the inner tube surface.

It’s not so much the coolant flow that creates cavitation. It’s the speed in which the object moving through the liquid separates the bonds of the fluid and creates an air bubble/void that then collapses on itself like a mini explosion and eats away at the material. In a IC engine it’s the waterpump impeller in a boat it’s the prop.

I still haven’t seen a actual idea or anything produced by you and instead you have others explain things for you and this thread becomes even less informative since you have provided literally nothing.

You should let us know about the SBC thermostat compared to its lack of a bottom spring as on the OE designed Stat

What about radiator end tanks and that you actually prefer crimped on plastic and epoxy ?

I’m merely explaining different engineering differences of thermostats. I’m not sure which type the Hemi uses and since u have provided no information on anything really this is more for the poor people that sift through all the BS.

Fabbed aluminum end tanks are better than plastic and copper. Plastic crimp fails over time but cost a lot less to produce on large scale. Copper requires soldered connections which kills cooling even though copper is a better conductor of heat vs aluminum.

 

[HEMIMANN]

Hmmmm....last I checked my heat transfer tables, copper has a higher thermal conductivity coefficient than aluminum. I guess those must be wrong.

Also conducts electricity better too,lol

 

[blackbetty14]

Hmm I also said that copper is better at conducting heat than aluminum but the brazing materials is also counter productive and has less thermal transfer than aluminum so… how are copper rads manufactured? Lots of soldering the tanks and tubes to the end tanks. Also cost wise copper is not viable anymore. Aluminum. Is cheaper and easier to manufacture and while it’s less effective than copper at thermal transfer you can counter with increased size.

have you ever read stuff posted on line and just shake your head at the lack of facts or in some cases outright MS-INFORMATION being posted?

Also conducts electricity better too,lol

Ya don't say! Wanna bet it costs more?

 

[Mister Luck]

I don’t want to open a can of worms but in the past I can't remember ever seeing a copper radiator only brass.

They're good reads,but there's nothing new in the articles,that anybody with any experience in the high output world didn't already know. He also promotes stand alone oil coolers,unless you have a high volumne oil pump,an oil cooler can drop pressures down to dangerous levels under certain conditions. I'm not disagreeing with you,just pointing out some of the obvious downfalls when employed on a stock engine with a stock oiling system

In the early years of automobiles some of the first radiators employed copper tubes and end plates. Later, copper plated sheet metal tubes were used.
