Experimental data was generated by performing the experiment on a plate heat exchanger for water/water system, at different flow rate and different hot water inlet temperature, at steady state conditions. Overall heat transfer coefficient (U) is determined for the performance evaluation of plate heat exchanger. The thermal properties of water (thermal Conductivity, Specific heat and density) at...

Volumetric visualization has many practical applications, particularly in medical imaging. Usability of volumetric visualization algorithms depends on available means to select areas of interest in volumetric data that are to be visualized. A simple and sufficient method is a onedimensional transfer function that assigns colours to intensity values of the data. A drawback of this method is that...

in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas pr...

The effects of oxygen supply on the submerged fermentation of Ganoderma lucidum, a famous traditional Chinese medicinal mushroom, for simultaneous production of bioactive compounds—Ganoderma polysaccharide and ganoderic acid (GA) were studied. An initial volumetric oxygen transfer coefficient (KLa) value within the range of 16.4–96.0 h−1 had a significant effect on the cell growth, cellular mor...

Most of the biopharmaceuticals nowadays are produced by animal cells. The worldwide demand for a specific group of biopharmaceuticals, the monoclonal antibodies (mAbs), has significantly increased this last decade. The mAbs are used as therapeutics in particular against cancer and autoimmune disorders. Most of the mAbs are produced as recombinant proteins by mammalian cells which ensure human-l...

The gas transfer in aeration systems is broken into two processes: gas transfer at the bubble interface and gas transfer at the water surface. Experiments were conducted to separate these two sources of dissolved gas. Oxygen absorption was measured in a laboratory tank with air being diffused through a porous diffuser and then with nitrogen gas being diffused. The combination of these experimen...

An experiment was developed using aeration of water for demonstrating the phenomenon of mass transfer. The demonstration was designed to provide both conceptual and practical insight of the mass transfer process. A bubble column fitted with a sieve tray was used to carry out the experiment. The air flow rate and hole size of the sieve tray were varied. Mass transfer coefficient was obtained fro...

In this work, the adsorption of carbon dioxide from model flue gas on different adsorbents has been investigated. Using simplified modeling, parameters such as the total mass transfer coefficient and the effective diffusivity have been determined. Experiments were carried out in two sections: firstly, adsorption of pure carbon dioxide on different adsorbents was measured at pressures ranging fr...
