The processed wood industry urgently needs a dryer to improve the quality of its production. One important components in is heat exchanger. To support durable transfer process, superior material needed. aim study was analyze effectiveness application cross-flow flat plate exchangers be used dryers and compare materials simulate on using Computational Fluid Dynamic simulations. results showed th...

drop plate technique has a priority and preference compared with the spread plate procedure, because of less time, quantity of media, effort requirement, little incubator space, and less labor intensive. the objective of this research was to compare the accuracy and fidelity of drop plate method vs. spread plate method by parametric and nonparametric statistical tests. for bacterial enumeration...

The influences of interactions between copper plate and nano-water droplets on wettability with different solid–liquid potential parameters were studied, the spread was compared analyzed using molecular dynamics method. diameter droplet spreading amount water molecules adsorbed gradually increased parameters, whereas absolute energy value also increased. Negative represents attraction force sol...

This paper reports the thermal performance of a new cylindrical solar collector based on an experimental investigation with this difference that instead of the collector tube with absorbent coating, coil into a spiral copper tube is placed in the center of the collector. The spiral shape of the tube, heat transfer without disruption or increase the heat transfer area, is increasing. In this cas...

The hydrodynamics that occur in the space between the electrode plates in copper electrowinning (EW) are simulated using a computational fluid dynamics model (CFD). The model solves for the phases of gas oxygen bubbles and electrolyte using the Navier–Stokes equations in a CFD framework. An oxygen source is added to the anode, which sets up a recirculation pattern. The gradients in copper near ...

Heterotrophic bacteria (11 genera, 14 species, 25 putative strains) were isolated from drinking water, identified either biochemically or by partial 16s rDNA gene sequencing and their adherence characteristics were determined by two methods: i. thermodynamic prediction of adhesion potential by measuring hydrophobicity (contact angle measurements) and ii. by measuring adherence to eight differen...
