低分子凝胶剂和金属颗粒对JP-10凝胶燃料流变特性的影响
Influence of Low-molecular-weight Gelators and Aluminum powder Powders on the Rheological Properties of JP-10 Gel Fuel
摘要
Abstract
Abatract:The gelation of gel fuel is achieved by incorporating varying content of low-molecular-weight gelling agent.The rheo-logical properties of the resulting gels are systematically investigated by introducing Al powder with different particle sizes.Key rheological parameters,including shear-dependent viscosity,thixotropic behavior,and linear viscoelastic properties,are ana-lyzed to evaluate the effects of gelling agent content,Al powder content,and particle size.The results demonstrate a pro-nounced shear-thinning behavior,with the gel viscosity decreasing by approximately four orders of magnitude as the shear rate increased from 0.01 s-1 to 100 s-1.Increasing the gelling agent content led to enhanced viscosity,improved recovery ability,and higher yield stress,with a more pronounced frequency dependence observed at higher content.The incorporation of Al powder significantly increases both gel viscosity and relaxation time,with nano-sized Al particles exerting a more substantial effect than micron-sized particles.Furthermore,the addition of surfactants and elevated temperatures results in a marked reduction in gel viscosity,accompanied by a concurrent decrease in both the storage modulus(G′)and loss modulus(G″).The incorporation of aluminum powder reduces the dependence of recovery rate on gelling agent content.Also,both surfactants and temperature sig-nificantly influence the rheological properties of the gel.The viscosity,storage modulus,and loss modulus of the gel system de-crease with increasing surfactant content and temperature.关键词
