More advanced fire behavior

Right. I have seen a gas station explode so bad it's wiped out the surrounding building.

 

That's in the right concentration. You won't get that in a fuel tank. The only place you get that in a car is within the pistons on the engine. Which are too small and strong to let the tiny explosions that power the car out.

 

I like this Idea very much, Just like the sounds that used to be in the game the fire we have now is probably just a temporary placeholder that will be replaced later by more advanced simulation. This is a good idea AIM. There are all sorts of cool possibilities with a more advanced fire simulation. There could be stuff like car engines exploding, gas tanks going up in a ball of fire and lighting other cars on fire. now that temperature simulation is implemented for engines, perhaps fire could actually have simulated heat signatures. This would allow fire to spread after the correct temperature was achieved, or the game could have friction simulation that, in extreme cases could play a role in spontaneous combustion. The way the gas tank explodes could be different depending on how much fuel is in the tank, lots of fuel=slow burn, nearly empty=more forceful explosion. Once fires actually create simulated heat the Developers could implement cool stuff like melting of the car parts. Maybe, even fire catching in the environment, similar to the tire skid marks, a burning car could actually leave trails of burning gas draining from the gas tank. Plus, think of all the epic mods people could make with a more advanced pyrotechnic simulation. . .

 

Right. I like the thought, but still it will expand quickly causing a burst of oxygen and fuel. Causing and outburst of flame.

I like this thought too

 

I guess it all gets down to one's interpretation of what an 'explosion' is. BLEVE's are indeed scientifically
classified as an 'explosion' so therefore car fuel tanks under the right conditions can 'explode' in the same
way a tanker truck will 'explode' when full of fuel. The same principle applies to anything 'flammable', when put
under pressure and heated it will 'explode', gun powder, fire works, rocket fuel... all sorts of stuff.

The existence of Hollywood is killing the human race.

 

Movies get cars wrong pretty much every time one goes flying into the air after catching on fire. Cars don't explode like that. And they rarely burst into a giant fireball. Both of those misconceptions are due to movies and video games (I'm looking at you, GTA) massively exaggerating car fires. Cars don't fly into the air when the fuel tank ignites. A fireball forms, not an explosion. Even then, many minutes pass before the fuel tank will get hot enough and the fire aggressive enough for that to happen. Here are three examples of how car fires actually work:

 

Great, not only is this a dismal showcase of undertrained bureaucracy riddled firefighting with
$1.5 million fire trucks but a midget firefighter thrown in for good measure. Priceless.

 

I take it nobody read through the math. Oh well. Let me put it in simpler terms and add a little to what I was saying before. In a spherical or cylindrical pressure vessel, the pressure will build and build and build. This is because the tensile strength in a spherical or cylindrical container is very, very strong. This tensile strength gives us the ability to build, for example, pressurized aircraft and strong gas tanks. This is why spherical pressure vessels need safety features such as an automatic release valve. And that is only if the fuel to air mixture is in the correct proportions. In a car, however, the fuel tank is in the shape of a box. This allows the tank to leak at the edges before bursting by redirecting the pressure to the corners. This is a good dissipation technique for BLEVEs, where the liquid boils and the resulting vapor takes up far more space than the container it occupies, and does not have to be caused by fire.
.

As a result, car BLEVEs are quite rare, and even when they do happen, they are really quite small. Not nearly enough for the Hollywood-like effect of lifting the car into the air. That only happens with some very powerful car bombs, and there is not enough fuel to air in the tank to explode. The car's gas tank will leak before exploding and then create a rapid-burning fireball, not an explosion. So car explosion, no. Car to car fire spreading, however, is a thing I would definitely like to see incorporated into the game.

 

Great level headed post. This subject came up a couple of years ago and ended in a ridiculous flame war
filled with butthurt....it was awesome.

I'll take your post to heart because it completely makes sense to a logical reasoning mind.

 

We could take the middle ground and implement terrorist car bombs for the H-Series.

 

This fire behaviour is not needed until fire actually can do some real damage to the car.

 

I like your thinking and I agree. When I say explosion, I don't mean like a bomb explosion, i mean like a little flash of energy that could have the power to destroy the back or front of a car. Engines normally don't explode themselves, and nether do gas tanks. But, when the pressure builds to a certain point, the tank cannot hold the pressure that is building outside. Its not the gasoline itself that is flammable, but its the fumes. So when the gas tank "breaks" if you will, the vapors expand rapidly, creating wha we see as a "fireball" or "mini explosion".

 

Dude you have played too much GTA.
And even if you put gasoline i a bowl and light it up it doesn't explode it just burns VERY rapidly.

 

I don't play GTA.

Have you payed attention to any of my recent posts? If you have read any of them you would know what I mean by "explosion".

 

I believe the word you are searching for is 'deflagrate'.

 

I feel terrible in saying that i would have so much fun crashing the H series into a crowd of dummies and blowing it up.

 

That's a little risky posting this, considering what happened in Belgium.

 

2 edgy 4 u.

No but really, terrorists are terrible, terrible people. My heart and condolences go out to those in Belguim, and they didn't deserve what happened to them.

 

Hmm...nice use of tact.
