This paper summarizes the practical use of CFD (Computational Fluid Dynamics) using a commercially available package, FLOTHERM [1], in a tight and highly competitive marketplace to produce a functional pre-production piece of telecom gear with no prototyping for thermal issues. The paper highlights the direct production, noprototype, analytical thermal performance verification of a small CMTS (Cable Modem Termination System) used in telecom applications.

Vertical Support

Extensive soil temperature measurements have been taken for more than two years in a field test designed to monitor the performance of thermal vertical support members used to support elevated sections of the trans-Alaska pipeline as it crosses marginal permafrost. Thermal aspects of the design are summarized and soil temperature data are presented which demonstrate the ability of the overall thermal vertical support member system to protect the surrounding permafrost.

The current study experimentally investigates the heat transfer augmentation on the novel axial corrugated heat exchanger tube in which the spring tape is introduced. Air (Pr = 0.707) is used as a working fluid. In order to augment the thermohydraulic performance, a corrugated tube with inserts is offered. The experimental study is further extended by varying the important parameters like spring ratio (y = 1.5, 2.0, 2.5) and Reynolds number (Re = 10 000–52 000). The angular pitch between the two neighboring corrugations and the angle of the corrugation is kept constant through the experiments at β = 1200 and α = 600 respectively, while two different corrugations heights (h) are analyzed. While increasing the corrugation height and decreasing the spring ratio, the impact of the swirling effect improves the thermal performance of the system. The maximum thermal performance is obtained when the corrugation height is h = 0.2 and spring ratio y = 1.5. Eventually, correlations for predicting friction factor (f) and Nusselt number (Nu) are developed.
