Thermal Effects Which May Result in the Unexpected Ignition of Gaseous Mixtures

Abstract

When gases are admitted rapidly to a vessel the temperature may rise several hundred degrees in some circumstances. A simple formula involving the specific heat ratio, thermal conductivity and molecular weight of a gas is derived which successfully describes the maximum value of this temperature pulse as a function of temperature and pressure for a variety of gases. Safety applications and corrections to measurements of ignition limits and ignition delay times are discussed.
