WebSecondary break-up is assumed to be controlled by the droplet Weber Number (We) which is defined as the ratio of the inertia forces to the surface tension forces: We = ρ a D d u rel 2 / σ f (3) where ρ a - ambient … WebSurface tension is one of the key properties that directly affects fuel atomization. A large value of this property makes the formation of small droplets difficult, hampering the … Web1. The surface tension of standard hydrocarbons of jet fuels at 20°C is directly proportional to the fuel density. 2. The temperature dependence of the surface tension of jet fuels is represented with complete accuracy by the equation if we represent the critical temperature by its mean effective value. 3. clbpt listening test
