Description


Qu'est ce que la flamme? Du gaz en combustion qui rayonne du fait de sa température interne très élevée due aux chaleurs de décomposition du carburant et du comburant. Une flamme est à considérer comme un sous-système d'un ensemble plus vaste : le volume de gaz qui éxiste tout autour. Car en effet, la flamme d'une bougie existe parce que le dioxygène de l'air se décompose avec la glycérine de la bougie pour former du dioxyde de carbone. La chaleur de combustion étant très élevée, le gaz carbonique formé est chaud. On a donc différence de température entre le gaz de départ (O2) et le gaz d'arrivé (CO2). Or l'élévation de la température au niveau macroscopique se traduit par une accélération de la vitesse des molécules des gaz au niveau microscopique. Ainsi un apport énergétique dù à la combustion de la flamme (réaction exothermique) augmente considérablement la violence et la fréquence des collisions entre molécules, ce qui tend à les espacer. Donc les gaz chauds sont moins denses que les gaz froids. Les gaz chauds et froids vont donc s'interchanger leurs places en fonctions de leurs densités. Si les gaz sont en quantités très importantes, et que les charges de l'allumage sont à un niveau critique, les explosions successives peuvent alimenter un faux soleil...un énorme feu spatial ! What is the flame? Combustion gas which radiates because of its temperature interns very high due to heats of decomposition of the fuel and the combustive one. A flame is to be regarded as a subsystem of a vaster unit: the volume of gas which exists around. Because indeed, the flame of a candle exists because the dioxygene of the air breaks up with glycerin of the candle to form carbon dioxide. The heat of combustion being very high, the formed carbonic gas is hot. One has thus difference in temperature between starting gas (O2) and the gas d' arrived (CO2). However the rise in the temperature at the macroscopic level results in an acceleration the speed of the molecules of gases at the microscopic level. Thus an energy contribution dù with the combustion of the flame (exothermic reaction) increases considerably the violence and the frequency of the collisions between molecules, which tends to space them. Thus the hot gases are less dense than cold gases. The hot and cold gases thus go between to interchange their places according to their densities. If the gases are in very large quantities, and that loads of the lighting are on a critical level, the successive explosions can feed a false sun… an enormous space fire!

fire in space must mean a new sun system is being born, perhaps from the ashes of an old one!
