Resumen

Методом рентгеновской дифракции исследованы фазовый состав и структурные свойства нитрата калия KNO3 и его гетерогенных композитов с наноразмерным порошком оксида алюминия Al2O3 при различных концентрациях нанопорошка Al2O3. Установлено, что в композитах (1+x)KNO3+xAl2O3 образуется дополнительная, высокотемпературная, ромбоэдрическая фаза нитрата калия (фаза III) с параметрами решетки a=5.4644 Angstrem, c=9.0842 Angstrem. Обнаружено, что с увеличением концентрации нанопорошка Al2O3 содержание основной фазы нитрата калия (фаза II) значительно уменьшается, при этом растет относительная доля фазы

Resumen

Introduction: Comparative studies of phase transitions in nanocomposites on the base of KNO3 and Al2O3 films with pores of 240 and 45 nm were carried out. Experiment: The temperature dependences of the linear dielectric constant and the amplitude of the third harmonic were measured. The measurements were carried out in the heating and cooling regime in the range from room temperature to 463 K. Anomalies, corresponding to structural phase transitions, were observed. Results & Conclusion: A considerable expansion of the temperature range of the potassium nitrate ferroelectric phase III was o

Resumen

(PEO+KNO3+Nano Al2O3) based Composite Polymer Electrolytes (CPE) has been prepared by using solution casting technique. In this technique, Poly (ethylene oxide) (PEO) and KNO3salt were dissolved separately in methanol and they were mixed together. Nano alumina (Al2O3) (particle size ~10nm) was doped to mixed solution and stirred for 24hrs. X-ray diffraction (XRD) technique has been obtained to determine complexation of salt and polymer in composite polymer electrolytes. Ionic and electronic transference numbers of these composite polymer electrolytes has been calculated by using Wagner’s polar

Resumen

HITEC salt (NaNO2-NaO3-KNO3) and solar salt (NaO3-KNO3) are typical molten salts used in concentrated solar power. Adding nanoparticles is an effective method to improve the thermo-physical properties of pure salt. It is indispensable to experimentally study the rheological behaviours of salt seeded with nanoparticles, which can increase the specific heat capacity of pure salt. In this work, the viscosities of HITEC salt were measured with different shear rates in the temperature range of 200 °C to 450 °C firstly, while those of solar salt were measured in the temperature range of 250 °C to 50

Resumen

In this study, the thermal characteristics of a high-temperature latent heat thermal energy storage system assisted by highly conductive nanoparticles and finned heat pipes are investigated numerically. A transient two-dimensional model is developed using the commercial CFD package of ANSYS-FLUENT18.2 to analyze the thermal performance of the storage unit during the charging process. Copper oxide (CuO) and aluminum oxide (Al2O3) are the nanoparticles introduced to enhance the thermal conductivity of the phase change material (PCM) which is potassium nitrate (KNO3) with melting temperature of 3
