Etude sur l‘influence de la puissance délivrée sur la consommation d’e-liquide (en anglais)
By Sébastien Soulet, Jérémy Sorin, Charly Pairaud, Maud Mercury, Hélène Lalo
Each e-cigarette user observe that more they increase power, more they produce vapor (others parameters being fixed). Likewise an important vapor generation lead to a high e-liquid consumption. We speak usually about couple « power/resistance value » to describe heating conditions, although the resistance value being not the influential parameter. Indeed, contrary to the commun though, we assume that the essential factor is the resistance’s surface. We introduce here the concept of power flux density. It’s defined as the ratio of the power delivred to the external surface of the resistance. We demonstrate that resistance’s surface is more important that resistance’s value for given power and liquid. We have studied e-liquid consumption, by-products generation and connected them to power flux density. Thanks to these results, we are able to give recommendations for « safer » practices (under these study’s conditions).
