The numerical analysis of boundary layer effect is one of the major concerned problems in boundary element method (BEM). The accuracy of this problem depends on the precision of the evaluation of the nearly singular integrals. In the boundary element analysis with direct formulation, the hyper-singular integral will arise from the potential derivative(More)

The parabolic-trough solar concentrator is the key component in parabolic-trough solar thermal power plants. The parabolic-trough solar concentrator is designed in this paper. It was analyzed under operational condition and under snow load. The model of the coefficient of accumulated snow with the different rotational angle is established. The coefficient(More)
