| Abstract | ||
| An experimental study on laminar flame speed of the premixed Iraqi liquefied petroleum gas (LPG)-hydrogen /air flames is conducted in a centrally ignited constant volume chamber specially constructed by the authors; at different initial pressures (0.1-0.3MPa) and initial temperature of (308 K). The tests are carried out at a mixture equivalence ratio ranges from 0.8-1.3. The investigated blends of hydrogen are 0-80% by volume . Experimental results show that the effect of hydrogen addition becomes obvious when the hydrogen blend is larger than 60%. When hydrogen blending 80%, the laminar flame speed of LPG also increases from (2.2-4.75 m/s) for stoichiometric mixture at atmosphere pressure. Increasing initial pressure from (1-3 bar), reduces stretched laminar flame speed of LPG-air mixture from (2.2-1.5 m/s) . | ||
