Possibility of using a bi-directional impulse turbine in a thermo-acoustic engine

Thermo-mechanical modeling of a high pressure turbine blade of an airplane gas turbine engine

During their operation, modern aircraft engine components are subjected to increasingly demanding operating conditions, especially the high pressure turbine (HPT) blades. Such conditions cause these parts to undergo different types of time-dependent degradation, one of which is creep. A model using the finite element method (FEM) was developed, in order to be able to predict the creep behaviour...

Thermo-Mechanical Fatigue Life Assessment of a Diesel Engine Piston

a swot analysis of the english program of a bilingual school in iran

با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...

A Satisficing Bi-Directional Model Transformation Engine using Mixed Integer Linear Programming

The use of model transformation in software engineering has increased significantly during the past decade, with the ability to rapidly transform models and ensure consistency between those models being a key property of Model Driven Architecture. However, these approaches can be applied to a wide variety of different model types and some of these models and associated transformations require d...

Efficiency Assessment of Acoustic Cabin for Providing Acoustic Comfort in Turbine Unit of a Thermal Power Plant

Background and Objective: A practical method for noise control in environments with different noise sources is designing an acoustic cabin for the workers. In this regard, this study aimed to assess the efficiency of the acoustic cabin in a typical turbine unit of a thermal power plant to provide acoustic comfort. Materials and Methods: Measurement of the noise level and spectrum, as well as v...
