Energy conservation equation Expressing the diffusive flux according to Fick´s law Schmidt number: ratio of the rate of momentum transport to the rate of mass transport Prandtl number: ratio of rate of momentum transport to the rate of energy transport Lewis number: ratio of rate of energy tr...
This paper is devoted to the study of semilinear degenerate elliptic boundary value problems arising in combustion theory that obey a general Arrhenius equation and a general Newton law of heat exchange. Our degenerate boundary conditions include as particular cases the isothermal condition (Dirichlet ...
Simulating Combustion Using the General ScalarThe scalar transport equation can be used to crudely simulate combustion. There are three processes which can limit the rate at which combustion proceeds:Macro-mixing - The large eddies of fuel and oxidant combine or interact by the action of convective...
we see that the equation is not balanced. There are only 2 atoms of hydrogen on the reactant side of the equation, while there are 4 atoms of hydrogen on the product side. We can balance the above equation by adding a coefficient of 2 in front of the formula for hydrogen. ...
By plotting the capacitive current at 0.05 V versus RHE against the scan rates, the Cdl was obtained as half of the corresponding slope, and the ECSA was derived from the equation ECSA = Cdl/Cs, where Cs is the specific capacitance. The Cs for a flat surface was in the range ...
Alkanes react with oxygen (combustion) and with halogens (halogenation).Exercises Why do alkanes usually not react with ionic compounds such as most laboratory acids, bases, oxidizing agents, or reducing agents? Write an equation for the complete combustion of methane (CH4, the main component of...
We then used bivariate analysis and structural equation modeling (SEM)29 to assess fertilizer impacts, and disentangle the relative contributions of diversity and asynchrony to stability (Fig. 1e). Results and discussion Fertilization effects on diversity, asynchrony, and stability Analyses of variance ...
and the ECSA was derived from the equation ECSA = Cdl/Cs, whereCsis the specific capacitance. TheCsfor a flat surface was in the range of 20–60 µF/cm2, and a value of 40 µF/cm2was adopted here to roughly calculate the ECSA. The stability was measured at a current de...
problems involving partial differential equations is to designate whether solutions to a given equation develop a singularity. The blow-up problem can have an impact on the physical relevance and validity of the underlying model. Therefore, it is interesting to solve and characterize this type of ...
