On the determination of the laminar burning velocity from closed vessel gas explosions

Accurate analytical models for fractional pressure rise in constant volume combustion

“…A linear x(p) relation, first introduced in their famous text book [1], is still used a lot in evaluating laminar burning velocities [4][5][6][7][8][9].…”

Impact of dissociation and end pressure on determination of laminar burning velocities in constant volume combustion

“…(2) and (5) leads to differences in S L of a factor γ u /γ b . This might explain the results of Dahoe and De Goey [8], who used Eq. (2) and found burning velocities 5-10% larger than literature values.…”

“…For this reason, the terms with j = n are treated differently from the others in Eqs. (8) and (9). The increment x n in mass fraction burnt in the nth shell, together with the burnt temperature of that shell T bn immediately after burning, are obtained by analytical solution of Eqs.…”

“…As a consequence, there are still many authors who prefer the simplicity and ease-of-use of the linear relation (2), as witnessed by a number of recent publications [8][9][10][11][12][13]. Obviously, such analytical approaches have clear advantages.…”

Miniaturization limitations of HCCI internal combustion engines

“…On the macro-scale, residence time is always long enough and is never a limiting factor. Decreasing the combustion chamber's dimensions leads to significant reduction of residence time since the flow speed cannot be reduced accordingly [11]. In order to maintain a working cycle and sufficient power output, higher engine velocities must be maintained.…”
