Flame Spread and Group-Combustion Excitation in Randomly Distributed Droplet Clouds with Low-Volatility Fuel near the Excitation Limit: a Percolation Approach Based on Flame-Spread Characteristics in Microgravity

Autor: Herman Saputro, Masato Mikami, Takehiko Seo, Hiroshi Oyagi

Publikováno v: Microgravity Science and Technology. 30:419-433

Stable operation of liquid-fueled combustors requires the group combustion of fuel spray. Our study employs a percolation approach to describe unsteady group-combustion excitation based on findings obtained from microgravity experiments on the flame

Flame-spread probability and local interactive effects in randomly arranged fuel-droplet arrays in microgravity

Autor: Hisashi Shigeno, Naoya Kojima, Hiroshi Oyagi, Masato Mikami

Publikováno v: Combustion and Flame. 156:763-770

We investigated the flame-spread characteristics of randomly arranged fuel-droplet arrays in microgravity. Flame-spread probability was calculated based on a percolation model with the flame-spread-limit distance of evenly-spaced n-decane droplet arr

Effects of Fuel Volatility on Flame Spread along Fuel Droplet Arrays in Microgravity

Autor: Naoya Kojima, Hiroshi Oyagi, Masato Mikami, Osamu Moriue, Masao Kikuchi

Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 71:2769-2775

Microgravity combustion experiments of fuel droplet arrays were conducted with different fuel volatilities. N-octane, n-decane and n-hexadecane were used to examine effects of volatility. Experimental results showed that the flame spread rate took a

Flame-Spread Behavior of Fuel-Droplet Arrays With Uneven Inter-Droplet Distance at High Temperature in Microgravity

Autor: Mikami Masato, Naoya Kojima, Kazuki Yagi, Hisashi Shigeno, Hiroshi Oyagi

Publikováno v: ASME/JSME 2007 Thermal Engineering Heat Transfer Summer Conference, Volume 1.

This research experimentally studied flame-spread behavior of fuel-droplet arrays with uneven inter-droplet distance at high temperature in microgravity. In experiments, first, n-decane droplets were generated in room-temperature air. Next, the dropl
