[ 1 ] - Numerical simulation of transient natural gas flow in pipelines using high order DG-ADER scheme
To increase the numerical accuracy in solving engineering problems, either conventional methods on a fine grid or methods with a high order of accuracy on a coarse grid can be used. In the present research, the second approach is utilized and the arbitrary high order Discontinues Galerkin Arbitrary DERivative (DG-ADER) method is applied to analyze the transient isothermal flow of natural gas th...
[ 2 ] - Thermal simulation of two-phase flow in under-balanced drilling operation with oil and gas production
The accurate prediction of wellbore temperature distribution helps to accurately estimate well pressure profile and bottom-hole pressure (BHP) which is important in the under-balanced drilling (UBD) operation. In this paper effect of temperature variation due to heat transfer of drilling fluid with the formation and also oil and gas production from the reservoir into the annulus in under-balanc...
[ 3 ] - بررسی عددی انتقال حرارت مختلط درون یک حفره حاوی نانوسیالات غیرنیوتنی با استفاده از مدل دوفازی مخلوط
در تحقیق حاضر، انتقال حرارت جابجایی مختلط در حفره ی پر شده از نانوسیال غیرنیوتنی با استفاده از مدل دوفازی مخلوط شبیه سازی شده است. نانوسیال آب- مس در این مسئله از خود رفتار سیالات رقیق شونده‌ی برشی را نشان می‌دهد. تأثیر رفتار غیرنیوتنی سیال با استفاده از مدل قانون توانی برای مقادیر مختلف شاخص قانون توانی بررسی شده است. پس از اعمال معادلات حاکم و مدل‌های مورد نظر در کد محاسباتی، اعتبارسنجی آن با...
[ 4 ] - Investigation of influential factors on well temperature for gas-liquid two-phase flow in under-balanced drilling operation
Analysis of the drilling fluid temperature due to heat transfer of drilling fluid with the formation in under-balanced drilling operation is the main objective of this study. Gas-liquid two-phase flow model considering thermal interaction with the formation is used to numerically simulate a well with real dimensions. In the present study, the continuity, momentum, and energy equations are devel...
