A second-law analysis of a gravity-driven film of non-Newtonian fluid along an inclined heated plate is investigated. The flow is assumed to be steady, laminar and fully-developed. The upper surface of the liquid film is considered to be free and adiabatic. The effect of heat generation by viscous dissipation is included. Velocity, temperature and entropy generation profiles are presented. The ...
The steady-state fully-developed laminar flow of non-Newtonian power-law fluids is examined in a circular microchannel with slip boundary condition and under an imposed constant wall heat flux. Effects of slip as well as the hydrodynamic and thermal key parameters on heat transfer and entropy generation are investigated. The results reveal that increasing the Brinkman number and the flow behavi...
OBJECTIVES To investigate the link between cigarette smoking and muscle strength in Japanese men. METHODS We used data on 4249 Japanese men, aged 43.3±13.9 years, in this cross-sectional investigation study. Grip strength and leg strength were measured as indicators of overall muscle strength. Meanwhile, subjects' cigarette smoking habits were recorded by trained medical staff. The effect of ...
هدف اصلی این پروژه شبیه سازی رفتار جریان سیالات shear thinning در محیط متخلخل با نفوذپذیری بالا توسط روش المان محدود می باشد. با توجه به میزان تخلخل محیط و عدد رینولدز، مدل های مختلفی برای جریان در محیط متخلخل ارائه شده اند. در شرایطی که سرعت جریان به اندازه کافی پایین باشد و بتوان از اثر اینرسی صرف نظر کرد، معادله brinkman میتواند به خوبی برای پیش بینی رفتار جریان در محیط متخلخل استفاده شود. د...
In the present work, the scattering differential cross section has been investigated for ion-multi electron atoms collision in the charge transfer channel. For this purpose, an active electron model was implemented and the collision process was considered as a three-body impact in the high energy range. A semi-classical formalism was used with the eikonal distorted wave function to describe the...
We prove continuous dependence of solutions of the Brinkman–Forchheimer equations on the Brinkman and Forchheimer coefficients in H1 norm. c © 2005 Elsevier Ltd. All rights reserved.

Abstract In this paper, we derive some estimates for the 3D non-autonomous linearization Brinkman-Forchheimer equation with singularly oscillating forces together with the averaged equation.
This retrospective study aimed to evaluate radiation-induced pneumonitis (RIP) and a related condition that we define in this report--prolonged minimal RIP (pmRIP)--after stereotactic body radiotherapy (SBRT) for Stage I primary lung cancer in patients with chronic obstructive pulmonary disease (COPD). We assessed 136 Stage I lung cancer patients with COPD who underwent SBRT. Airflow limitation...
