| Abstract | ||
| در این مقاله، اثر افزودن گاز هیدروژن به مخلوط گازهای متان وهوا در یک محفظه احتراق میکرو با استفاده از روش عددی سه بعدی بررسی می شود. در ابتدا، نتایج پژوهش حاضر در تعیین دمای دیواره محفظه احتراق با نتایج تجربی و عددی پژوهش گذشته مقایسه می شود. با تائید درستی حل عددی پژوهش حاضر، تاثیر افزودن هیدروژن به مخلوط متان و هوا در توزیع دما، فشار و گازهای خروجی به صورت عددی بررسی می گردد. نتایج عددی نشان می دهد که افزایش درصد هیدروژن در مخلوط متان و هوا منجر به تغییرات غیر خطی در سرعت، فشار و دما می شود. به علاوه، نتایج نشان می دهد که افزایش درصد هیدروژن به 2.5% و 5% به ترتیب ماکسیمم سرعت گازهای خروجی و حداقل دما را در محفظه احتراق ایجاد می نماید | ||
