“…The velocity distribution and pressure difference values for different cases give orientated opinion about the importance of roof on the houses. This important contribution will supply a benefit on decreasing the energy costs in winter days and improving the Flow structure around the bluff body (rectangular and pyramid geometries) [21].…”

“…Usually classified as being low Reynolds number flow due to the small velocities and length scales encountered. The formulation for Launder and Spalding's turbulence model consists of two transport equations, one equation to describe the kinetic energy of turbulence and a second related to the rate of turbulent dissipation [21]. As it has been stated in many previous studies, k À e model is valid for low air velocities and it is also used in this work [22].…”

“…Certainly, the practical usefulness of the model has been demonstrated by many workers, including Rodgers et al [233], Dhinsa et al [234], and Choi et al [235]. The latter report that the LVEL model was as effective as the more advanced two-equation models for simulating rack-mounted servers, with the big advantage being that ''significant computation time can be saved (factor of three or higher), especially when conducting transient CFD simulations or when making steady-state runs with different rack settings".…”

Starting from early work on combustion, and his unique work in mass transfer theory, Spalding's unpublished ''unified theory" is described briefly. Subsequent to this, developments in algorithms by the Imperial College group led to the birth of modern computational fluid dynamics, including the well-known SIMPLE algorithm. Developments in combustion, multi-phase flow and turbulence modelling are also described. Finally, a number of academic and industrial applications of computational fluid dynamics and heat transfer applications considered in subsequent years are mentioned. Crown

“…This subject has been frequently discussed in the literature [5,8,9,11]. As discussed in the preceding paragraphs, the accuracy of a complex numerical CFD model is not necessarily greater than a first-order analysis, especially if the modeling process is not appropriately performed with consideration of both physics modeling and numerical accuracy.…”

assure that the intended product reliability and life goals are realized.Among the many different categories of electronic products, thermal design of telecommunication equipment poses special challenges due to the high reliability (99.999 percent or five nines uptime) requirement [10]. For example, as a result of the five nines availability requirement, central office shelf level equipment in North America is required to be operational for short durations under ambient temperature conditions up to a maximum of 55°C and required to be operational for long durations subjected to 45°C ambient conditions. In contrast, data center equipment is required to be operational for short durations under ambient temperature conditions up to a maximum of only 35°C. Now, with the convergence of data, video, and voice (Internet, TV, and phone services), more functions and capacitiesand hence, more heat-are packed into a shrinking
