Thermal conversion technology of Chinese herb residues (CHR) becomes one the most promising technologies in large-scale clean utilization due to its short process and high efficiency. In this study, non-isothermal thermogravimetric analysis CHR samples without with K2CO3 (5%K- 9%K) was implemented at 300−1125 K heating rates 10−40 K/min. A model-free Starink method applied evaluate thermal deco...

In this paper we calculate the turbulent heating rates in the solar wind using the Kolmogorov-like MHD turbulence phenomenology with Kolmogorov’s constants calculated by Verma and Bhattacharjee [1995b,c]. We find that the turbulent heating can not account for the total heating of the nonAlfvénic streams in the solar wind. We show that dissipation due to thermal conduction is also a potential he...

Fiber metal laminate (FML) is a kind of lightweight material that has garnered much attention in recent years due to its excellent properties under tensile, flexure, and impact conditions. However, little been paid the evolution aluminum alloy during FML forming process. In this paper, effects specimen thickness non-isothermal process on creep behavior AA2024 alloy, which generally used FMLs, w...

In this paper the effects of the strain rate on the inelastic behavior and the self-heating under load conditions are presented for polymeric materials, such as polymethyl methacrylate (PMMA), polycarbonate (PC), and polyamide (PA66). By a torsion test, it was established that the shear yield stress behavior of PMMA, PC, and PA66 is well-described by the Ree-Eyring theory in the range of the co...

Bio-oil produced from the pyrolysis of sugarcane bagasse has potential to be used as a sustainable and renewable energy source. In present study, non-isothermal thermo-gravimetric analysis (TGA) (in N2 atmosphere) combustion air) bio-oil was investigated at three heating rates: 5, 10, 20 °C/min. The sample heated room temperature up 900 °C evolved gases in TG furnace were carried Fourier transf...

Amaranthus retroflexus or redroot pigweed is a second generation lignocellulosic fuel. Each biomass sample (leaves, inflorescences and stems) was pyrolyzed in lab-scale furnace, nitrogen atmosphere under non-isothermal conditions at heating rates of 10 °C/min until the furnace temperature reached 550 °C. The pyrolysis characteristics three major components were also studied through thermogravim...

Experimental results are reported for a U-shaped, free convection loop. The top of the loop is open to an isothermal reservoir. The horizontal leg and one vertical leg are heated at rates Q1 and Q2, respectively. The loop is filled either with water or a watersaturated porous medium. Symmetric heating and asymmetric heating favouring the ascending leg of the loop both yield stable flows. Asymme...

A model is developed to predict the precipitation kinetics and strengthening in Al–Cu–Mg alloys during non-isothermal treatments consisting of controlled heating and cooling. The prediction of the precipitation kinetics is based on the Kampmann and Wagner model. The precipitation strengthening by the shearable Cu–Mg co-clusters is modelled on the basis of the modulus strengthening mechanism and...
