Huang Yaoying,Ding Yuemei,Lv Xiaoman and Xu Bailin

Strategic Study of CAE 2014, Volume 16, Issue 3,   Pages 59-63

Abstract:

To the sluice pier concrete，temperature control and crack prevention is a complex and multi- factor problem of system optimization related to temperature control measures and material parameters. This paper tries optimal temperature control measures with the known concrete material thermodynamics parameters，takes minimum values of the relationships between the sluice pier concrete structure’s internal/surface principal tensile stress duration curve and tensile strength growth curve as inputs and the sluice pier superficial heat preservation effect，pouring temperature，pipe cooling temperature and duration time as outputs，establishes the neural network model of the optimal temperature control measures，takes the uniform design principle to have the temperature control parameter combination，adopts the pipe cooling finite element method（FEM）to simulate and analyze the temperature field and creep stress field of the sluice pier concrete structure with cooling pipe，and gets samples to train network to describe the nonlinear relationship between the relationship's minimumvalueof the structure's principal tensile stress duration curve and tensile strength growth curve and different temperature control measures. Inputting the appropriate relationship's minimum value of structure’s the principal tensile stress duration curve and tensile strength growth curve to the trained network，it can automatically select the optimal temperature control measures. The example shows that the neural network model of the optimal temperature control measures is feasible.

Heat transfer and fluid flow analysis of an artificially roughened solar air heater: a CFD based investigation

Anil Singh YADAV,J. L. BHAGORIA

Frontiers in Energy 2014, Volume 8, Issue 2,   Pages 201-211 doi: 10.1007/s11708-014-0297-7

Abstract: In this paper, the effect of rib (circular sectioned) spacing on average Nusselt number and friction factor in an artificially roughened solar air heater (duct aspect ratio, AR= 5:1) is studied by adopting the computational fluid dynamics (CFD) approach. Numerical solutions are obtained using commercial software ANSYS FLUENT v12.1. The computations based on the finite volume method with the semi-implicit method for pressure-linked equations (SIMPLE) algorithm have been conducted. Circular sectioned transverse ribs are applied at the underside of the top of the duct, i.e., on the absorber plate. The rib-height-to-hydraulic diameter ratio ( ) is 0.042. The rib-pitch-to-rib-height ( ) ratios studied are 7.14, 10.71, 14.29 and 17.86. For each rib spacing simulations are executed at six different relevant Reynolds numbers from 3800 to 18000. The thermo-hydraulic performance parameter for = 10.71 is found to be the best for the investigated range of parameters at a Reynolds number of 15000.
