The aim of this work was to study the effect of spray drying conditions on quality of coconut sugar powder and their characteristics. Effects of inlet air temperature (120°C, 150°C and 180°C) and maltodextrin concentrations (DE 9-12) at 10%, 20% and 30% (w/v) on physical properties of spray dried coconut sugar powder were investigated. Buchi mini spray dryer, model B-290, was used in this work....

The objective of this work was to investigate the influence of selected individual variables (binder content, inlet air temperature, and product endpoint temperature) of in situ fluid bed melt granulation on the granule particle size distribution and percentage of dissolved carvedilol using a three-factor, five-level circumscribed central composite design. Increased binder content had the effec...

The increasing use of fuels derived from oil, deepens concern about the fact that non-fossil fuels have to be considered as the fuels of the future. Among the alternatives, hydrogen produced from the abundant sources of water, seems to be one of the best, but it suffers drawbacks with regard to combustion, storage and transportation. The other alternatives are ammonia, produced from unlimited s...

A numerical investigation was conducted to study the heat transfer in an aircraft cabin and the effects of air distribution under different angle and inlet velocity conditions. The Reynolds-averaged Navier–Stokes equations and the low Reynolds number turbulence model were used to simulate the airflow in the cabin. Mathematical statistics was used to process the relevant data, and statistical re...

Cooling characteristics are given in terms of the variation of average blade temperature at mid-span with cooling-flow rate, Reynolds number, gas/cooling-air absolute temperature ratio, and, for the rotor, gas-stream incidence. Chordwise and spanwise variations of blade temperature are also presented. Measured pressure-drop characteristics indicate that in a gas-turbine engine, with the cooling...

One of the possible origins of High Cycle Fatigue in a compressor blade is the rotating stall under the influence of (rotating) inlet pressure or temperature distortion leading to a varying angle of attack on the compressor blades. This paper will be oriented towards the propagation of total pressure and total temperature nonuniformities in axial flow fans and compressors and their subsequent e...

Gas turbines play an important role in supplying power for the country especially in peak electricity load. The main disadvantages are the turbines, they produce large changes are a result of climate change. However, in times of peak electricity grid and at the same time warm months, can produce gas turbines under the effect of ambient temperature, the amount of reduced considerably. The method...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

SEGES Pig Research Centre tested three different types of supplementary air inlets in a farrowing house to evaluate the effect on the sows’ immediate environment during the summer. The three different types included trough valves, a single ceiling inlet per sow and transverse ceiling inlets in the section. No supplementary air inlets were installed in the control section. The primary parameters...

The objective of this work was to evaluate the influence of inlet air temperature and emulsion composition (total solid content and oil concentration), as well as its associated properties (viscosity and droplet size), on the microencapsulation of flaxseed oil by spray drying, using gum Arabic as wall material. Coarse emulsions were prepared by blending the flaxseed oil and the gum Arabic solut...
