Thermal stratification in solar storage tanks
The purpose of the work was to investigate the thermal stratification in solar storage containers. Three domestic thermally stratified hot water storage containers were designed with the main object of improving and stabilizing thermal stratification of the stored water as a means of improving the …

Mixing of Liquids in Large Tanks
… to model the mixing process in large storage tanks equipped with side-entry mixers.Terminal mixing times have been measured as a function of impeller speed, impeller diameter, liquid depth and impeller angle. it is shown that the indicator method for measuring mixing times yields results which …

Multiphase CFD modelling of stirred tanks
Stirred tanks agitated with Rushton turbines are commonly used in industry, for instance mixing processes and flotation systems. The need for more efficient systems in industries has led to the study of fluid flow within the tanks upon agitation; so that a better understanding of the phenomena can …

Design and control of equalization tanks.
The objective of this investigation was to develop a control strategy for the operation of an equalization tank upstream of a waste water treatment plant which utilizes the available equalization hold-up volume in such a manner that it reduces, optimally, diurnal fluctuations in both influent flow …

The Modernization of Large Power Transformer Tanks
… data retrieved from the search showed that the tanks of these LPTs are critical to their durability, longevity, and reliability. Therefore, the reliability of LPTs can be improved by the modernization of the LPT tanks by the replacement of the current LPT tank modern designs using other …

Turbulent mixing of unpremixed reactants in stirred tanks.
The turbulent mixing process between two liquid streams in a standard tank stirred by a Rushton turbine has been studied. Experimental measurements of concentration and segregation (fluctuating concentration) have been made for both reacting and non-reacting flows. For the non-reacting case, one …

Effects of earthquakes on partially-filled water tanks
… effects of earthquakes on partially-filled water tanks. The analysis is applicable to rectangular water tanks, which have received little attention to date. The analysis is relatively involved and includes the derivation of the equations of motion for the vibration of the whole of tank by means of …

Monitoring separation process in separator tanks by ultrasound technique
… levels in both horizontal and vertical tanks by analyzing the amplitude of ultrasound pulses. The remarkable innovation of this method is the exclusion of the time-of-flight data in the monitoring process. To estimate the liquid level, the traditional method has been to measure the time …

Mathematical simulation of dynamic behaviour of secondary settling tanks
… behaviour of full scale secondary settling tanks. The model was initially developed for and tested on laboratory scale data. It was then calibrated with full scale data and used to verify the flux theory by comparing the simulated predictions and the measured results. The simulations …

A hydrodynamic study of nickel suspension in stirred tanks
Many studies on solid-liquid mixing have been dedicated to low density particles at low solids concentrations. In the present work, computational fluid dynamics (CFD) simulation and experimental methods were employed to study suspension of high density particles (nickel) at high solids …

Finite element analysis of flows in secondary settling tanks
Secondary settling tanks (SSTs) form a crucial part of wastewater treatment plants. Besides having to produce the separation of suspended solids and clarified effluent the secondary settling tank is used to concentrate and recycle the settled sludge to the biological reactor. The efficiency of the …

Field study of performance of rectangular chlorine contact tanks
… of three types of rectangular chlorine contact tanks. Efficiency of the tanks was evaluated in terms of the type of initial mixing of the chlorine and fluid, location and configuration of the inlet and outlet structures, the influence of baffles and the effect of sludge deposits. Two unbaffled …
