چکیده

در مقالۀ حاضر تخمین شوک حرارتی در پروفیل شار حرارتی با داشتن توزیع دما به‌کمک فیلتر کالمن صورت پذیرفته است. برای این کار، ابتدا با محاسبۀ توزیع دما و اعمال نویز به‌صورت مصنوعی سعی می‌شود تا به شرایط آزمایشگاهی اندازه‌گیری دما نزدیک شد. در ادامه با استفاده از روش فیلتر کالمن، به بررسی تخمین آنی شارحرارتی پرداخته می‌شود که به‌صورت شوک حرارتی در مسألۀ مورد نظر ظاهر می‌شود. نتایج به‌دست آمده نشان می‌دهد که روش حاضر قادر است با دقت قابل قبول جهش شار حرارتی را تخمین بزند.

چکیده [English]

In this paper, the heat shocks in the heat flux profile are estimated with known temperature distribution using Kalman filtering. For this task, the temperature distribution is calculated and artificial noise is added to adequately simulate the real temperature measurements. Next by using Kalman filtering, estimation of online heat flux is assessed which appears as heat shocks in the discussed problem. Results indicate that the present method can accurately estimate jumps in the heat flux.
