Asymptotic theory of anisotropic plates and shells

A consistent theory for thin anisotropic layered structures is developed starting from asymptotic analysis of 3D equations in linear elasticity. The consideration is not restricted to the traditional boundary conditions along the faces of the structure expressed in terms of stresses, originating a new type of boundary value problems, which is not governed by the classical Kirchhoff-Love assumptions. More general boundary value problems, in...

Experiments on expansion and superheat processes of a CO2 cycle using microchannel evaporator

Experiments on expansion and superheat processes of a transcritical CO2 air conditioning system were done. In this study, the cross-sectional area of the expansion valve reduces from 8.195 to 0.091 mm2, the cooler pressure increases and the evaporator pressure decreases; the pressure difference between cooler and evaporator increases
