... power loss per fin for radiator configurations featuring 1, 5 and 15 fins, and the results are validated against a reduced semianalytical model. Findings The analysis reveals that the imposed mass flow rate boundary condition yields a higher average outlet temperature and approximately 5% lower...

...Behnam Rafiei; Hamed Masoumi; Mohammad Saeid Aghighi; Amine Ammar Purpose The purpose of this paper is to analyze the effects of complex boundary conditions on natural convection of a yield stress fluid in a square enclosure heated from below (uniformly and non-uniformly) and symmetrically cooled...

... by Rodi and Scheuerer (1985) is included for comparison reasons. The different procedures are first validated on the fully developed channel and pipe flow. Next, the turbulent flow over a backward‐facing step is considered. Finally, the influence of the inlet boundary condition for ϵ...

...Hussein Bazzi; Cong Tam Nguyen; Nicolas Galanis This work is concerned with the problem of the transient behaviours of the axisymmetric thermocapillary laminar flow occurring inside a half zone subjected to a variable thermal boundary condition during a heating process. The molten liquid with its...

... extending the scope of blood flow simulation (Sheu et al., 1999), we are prompted to conduct analysis on moving grids in the hope of simulating complex haemodynamics such as that considered in Taylor et al. (1998). Finite element analysis Transformation Boundary conditions Grids...
