“…The obtained results showed that the entropy level increased for higher Rayleigh numbers and high irreversibility ratios. Rathnam et al 21 analyzed entropy production caused by laminar natural convection inside tilted triangular enclosures with different base angles. The optimal shape and tilt angle beside the Rayleigh number were indicated in terms of minimum entropy and maximum heat transfer.…”

“…Analysis of the variation of average Bejan number with Da illustrated that the fluid friction irreversibility contributes significantly to the increase in total entropy generation. Rathnam et al [19] studied the influence of the Rayleigh numbers (Ra = 10 3 −10 5 ), the Prandtl numbers (Pr = 1.5 10 −2 −10 3 ) and the base angles (φ = 45° and 60°) on entropy generation during natural convection in isosceles triangular cavities for various base angles or tilt positions. They were able to determine the most suitable parameters as well as geometric configuration to minimize the entropy generation.…”

“…In the same way, Erbay et al [13,14], specify values which increase linearly with the Rayleigh number (Ra), starting at 10 -13 for Ra=10 2 to reach 10 -9 for Ra=10 6 , with constant steps of 10. Rathnam et al [15], use an order of magnitude analysis of parameters to evaluate the same ratio at 10 -3 . Magherbi et al [16], Ilis et al [17], De C. Oliveski et al [18], and Bouabid et al [19], consider this coefficient as an investigative parameter in the same way as the Rayleigh, or Prandtl numbers for example in [16], φ varies from10 −4 to 10 −1 and in [17-18-19], φ varies from 10 −4 to 10 −2 .…”
