| Research Abstract |
Steadiness of flame spread over electric wire has been studied experimentally as well as numerically(theoretically). With precise visualization and temperature measurement of wire during the flame spreading event, it is understood what is the mechanism to lead the unsteadiness and what is the condition to reach steadiness of the system. To verify this consideration, Pe-. correlation has been proposed and the verification is fulfilled. Applicability of B-number theory to describe wire combustion character was ensured via microflame study. Direct numerical simulation methodology was developed based on VOF method and enthalpy-porosity method and the precise prediction of growing event of heated molten polymer was successfully accomplished.
