This work investigates process-part quality relationships in terms of the internal and external defects and component microstructure relative to a feedstock subjected to 33 build cycles without replacement. To accomplish this, a volume of fluid mesoscale model consisting of three different powder ...
With the insulation applied as mentioned previously, the heating power applied to the test section was assumed to be equal to the power input from the power supply, and was calculated using the generalised power equation:(2)Q˙test=VIwhere V and I are the voltage and current provided by the...
Tm,o: the onset temperature of melting; ΔHm: the fusion curve enthalpy of heat absorption peak; Fw: the freezable moisture content. 1-SPPH, 2-SPPH and 3-SPPH represent the addition of 1 g/100 g, 2 g/100 g and 3 g/100 g of sweet potato protein hydrolysate to the frozen dough, ...
Ten kg of wet steam at 0.75 MPa has an enthalpy of 22,000 KJ. Find the quality of the wet steam. Vapor Quality:Imagine a substance during the vapor-liquid phase change. If we divide the mass of the vapor by the total mass of the substance, then ...
It was found that both swelling and deswelling data could be reduced to a universal scaling equation of the same general form as derived from renormalization group (RG) theory for flexible linear polymer chains in solutions. Introduction Gels have recently been of particular interest in connection ...
Hello i have to derive the quality factor Q i must start with Q=2\pi\frac{internal-stored-energy}{energy-loss-per-cycle} the quality factor should be in terms of λ so the last equation shall be Q=\frac{4\pi L}{\lambda (1-R)} i searched in google but i always get the Q-fac...
Determining what an adequate thermal process is has been transformed from an art to a science. Quantitative predictions of the impact of a particular thermal process in terms of safety and quality have become more common. Kinetic models can be developed to predict important parameters for process ...
Origin 2020 was used to plot the standard curve and obtain the regression equation: Y = 0.5208x-0.0146, R2 = 0.9984 (Fig. S4).Peptideextractionrate(%)=c×vm×100where: c, peptide concentration, mg/mL; v, volume of crude peptide extraction, mL; m, weight of raw materials, mg. 2.4....
The sub-models can, in terms of their parametrization, be classified as parametric and nonparametric (von Stosch et al., 2014). In parametric models, the number and the nature of the parameters are finite and fixed a priori based on the knowledge about the phenomena inside a process (...
is an “Auto Regressive Moving Average exogenous”(ARMAX)-based equation where the output signal vector y(t) contains the signals we want to model. The input signal vector u(t) can, as mentioned above, for example contain some variables from the temperature profile of the refining zone, pro...
