چکیده مقاله :
در اين مقاله روشي سريع براي شبيه‌سازي فرآيند گرمايش مايکروويو در مواد مخلوط به ويژه مواد آلي و ترکيبات نفتي معرفي مي‌شود. با بکارگيري روش FDTD در مواد واپاشنده و ارائه روش TD2(FD) که بر مبناي رابطه تلفيقي بين ميدان‌هاي E و D و يا بر اساس رابطه تفاضلي بين اين دو ميدان مي‌باشد مسئله فرآيند گرمايش مايکروويو مدل‌سازي و مشابه‌سازي شده است. با بکارگيري اين روش زمان طولاني و حجم حافظه زياد مصرفي براي تحليل محيط‌هاي واپاشنده بسيار بهبود پيدا کرده است. نهايتاً اين روش براي مشابه‌سازي فرآيند گرمايش مايکروويو در برخي از انواع نفت خام بکار گرفته شده و نتايج ارائه شده است.
A new method to simulate the microwave heating process in crude oils has been presented. Using convolution ( or differential) relation between E and H fields, (FD)2TD method is extracted by modifying the conventional FDTD technique for depressive materials. It is shown that the computer time and memory requirements to analyze and simulate the microwave heating process are extensively reduced. Eventually, the advantages of the technique to simulate the microwave heating process in crude oils are presented.
