It is confirmed that the slug flow absorber operates well at the low solution flow rate conditions.
The grooves are designed to obtain good absorber plate wettability, even at a low solution flow rate, resulting in a laminar solution flow regime.
This study deals with an experimental investigation for a counter-current slug flow absorber, working with ammonia water mixture, for significantly low solution flow rate conditions that are required for operating as the GAX (generator absorber heat exchanger) cycle.
Optimum operating conditions for the high efficiency nebulizer-short torch arrangement are generally similar to those of the direct injection high efficiency nebulizer: high RF power (1500 W), low nebulizer gas flow rates (0.09 L/min) and low solution uptake rates (5 85 μL/min).
Limited or absence of drainage and small available amount of solution are obtained with so-called micronebulizers, that is, working at very low solution delivery rates.
By reducing the film contraction in the transverse direction, the increase of plate surface temperature could enhance the wetted area significantly, especially for the low solution mass flow rate.
Since "failure to solve" had produced results, even if feeble, Hargrove told the computer to notify him of places where solution rates were unusually low.
This research work proves a better corrosion resistance of AZ31B magnesium alloy at the alkaline solution than the acidic and the neutral solutions, moreover, low corrosion rate was found at low concentrated solution and higher exposure time respectively.
The results show that the corrosion resistance of AZ61A magnesium alloy welds in the alkaline solution is better than that in the acidic and neutral solutions, moreover, low corrosion rate is found at low concentrated solution and longer exposure time, and the corrosion morphology is predominantly influenced by the distribution of β-phase.
However the stationary solution with low firing rate is locally asymptotically stable.
