Exothermic chemical reaction of magneto-convective nanofluid flow in a square cavity

International Journal of Thermofluids, 2022
We investigate the unsteady laminar convective magnetohydrodynamic nanofluids flow in a square cavity driven by an exothermic chemical reaction. Because exothermic chemical reactions are intrinsic in nanofluidic flow applications, we consider this ...

Controllable synthesis of SiC wrapped LDHs to reinforce microwave absorption and exothermic properties of styrene-butadiene-styrene (SBS) polymer modified asphalt

Materials Research Express, 2021
Combination of styrene-butadiene-styrene (SBS) polymer and layered double hydroxides (LDHs) has commonly applied in asphalt to improve anti-ultraviolet aging performance, but it can not afford the reparation of cracks caused by aging of asphalt.

Exothermic effect during torrefaction

Journal of Physics: Conference Series, 2018
There are presented the results of investigation of exothermal effect taking place during torrefaction process. Experiments were carried out with the help of thermoanalyzer SDT Q600, that gives opportunity to use methods of differential thermogravimetric analysis and differential scanning calorimetry, and at the lab-scale installation modelling the ...

Evaluation of the Heat Produced by the Hydrothermal Liquefaction of Wet Food Processing Residues and Model Compounds

ChemEngineering, 2022
Hydrothermal liquefaction has proven itself as a promising pathway to the valorisation of low-value wet food residues. The chemistry is complex and many questions remain about the underlying mechanism of the transformation. Little is known about the heat
