Full scale thermal testing of latent heat storage in wallboard

Full scale thermal storage tests were conducted in a room lined with PCM wallboard having latent heat storage capacity. The results were compared with those obtained from tests conducted in a similar room lined with ordinary wallboard. The research showed that PCM wallboard can function efficiently as a thermal storage medium which can be applied to peak load shifting, improved use of waste and solar heat as well as more efficient operation of heating and cooling equipment.

提高铌钽标准液显色反应能力并延长其有效贮存期的分光光度法研究

铌，钽的酒石酸，柠檬酸，草酸铵标准液的显色反应能力及有效贮存期，同铌，钽的原始标准溶液ｐＨ有很大关系，铌酒石酸标准液（原始溶液ｐＨ１．４），其显色反应能力仅在８０％～５０％之间（视放置时间长短而异），但如何采用ｐＨ４．５～５．０的铌酒石酸标准液，其显色反应能力达１００％，即使贮存４４０ｄ后，仍能保持原有的显色反应能力，铌柠檬酸标准液（原始溶液ｐＨ１．２），无论用本法（Ｎｂ－ＢＰＲ－ＣＰＢ法）还是用     

Pressure Behavior for Spherical Flow in a Reservoir of Non-Newtonian Power-Law Fluids

The pressure variations during polymer flooding of oil reservoirs for oil recovery projects can be used to analyze the flow in the reservoir which is especially useful for the partially perforated reservoirs. This paper presents a relationship between the viscosity and the shear rate which is similar to forms developed for radial flow (Odeh, A. S., Yang, H. T. ([1979]). SPEJ. AIME (Jun.) 155). The power-law viscosity model is used to give the variation of the fluid viscosity with the spherical radius for a mathematical model of unsteady spherical flow for non-Newtonian fluids with wellbore storage and skin. An analytical solution for the wellbore pressure responses derived in Laplace space is used to analyze the behavior characteristics at early and later times to interpret the well-test parameters. The pressure variations are similar to those for a Newtonian fluid at the early times, but at later times, the variation of the viscosity with the power-law exponent is important, so the pressure response differs from that for a Newtonian fluid. The solution has significance for interpreting well test parameters for non-Newtonian spherical flow.
