text: Liquid atomization is expected to be a key process in Flame Spray Pyrolysis,
as it determines the primary droplet size and velocity distribution, which represent
initial conditions for flame shape and temperature field. A well-defined manipulation
of atomization may be achieved by variation of nozzle geometry, injection parameter
or fluid properties. However, change of fluid properties, e.g. varying solvents
or increasing the precursor concentration, also influences the final particle
properties. In this work, the influence of precursor concentration on fluid properties,
spray and particle formation in Flame Spray Pyrolysis is experimentally investigated.
High-speed shadowgraphy and Phase-Doppler measurements are conducted in a semi-closed
combustion chamber with a well-defined burner geometry (SpraySyn burner) that
is based on a coaxial atomization principle. By adding precursor to the flammable
solvent, resulting spray characteristics, flame shape and appearance are changed
in color, shape and mean droplet size distribution. Compared to resulting mean
droplet sizes of pure solvent mixtures (D32, 22 μm), mean droplet sizes in the
center of the precursor flame at 30 mm above the burner are generally smaller
(D32, 18 μm). Persisting high share of small droplets in the droplet size distribution
are presented, that presumably origin from an accumulation of metal organic precursor
at the droplet surface during combustion, that acts as a diffusive barrier for
high volatility solvent and thus reduces droplet evaporation. Sufficiently high
above the nozzle exit, increasing the precursor concentration does not affect
the radial distribution of mean droplet sizes but leads to increased mean particle
sizes. More precursor presumably leads to higher concentrations of prime particles
in the flame, thus probability of particle collusion and agglomeration. High-speed
imaging at nozzle exit revealed random fluctuations of initial jet diameter, paired
with jet axis shifting around 1000 Hz. These superposed fluctuations determine
the initial conditions for atomization, induce pulsations in the flame and thus
initiate the entire chain of the particle synthesis process.

text: Prerequisite for an efficient cooling energy system is the knowledge
and optimal combination of different operating conditions of individual compression
and free cooling chillers. The performance of cooling systems depends on their
part-load performance and their condensing temperature, which are often not continuously
measured. Recorded energy data remain unused, and manufacturers’ data differ from
the real performance. For this purpose, manufacturer and real data are combined
and continuously adapted to form part-load chiller models. This study applied
a predictive optimization algorithm to calculate the optimal operating conditions
of multiple chillers. A sprinkler tank offers the opportunity to store cold-water
for later utilization. This potential is used to show the load shifting potential
of the cooling system by using a variable electricity price as an input variable
to the optimization. The set points from the optimization have been continuously
adjusted throughout a dynamic simulation. A case study of a plastic processing
company evaluates different scenarios against the status quo. Applying an optimal
chiller sequencing and charging strategy of a sprinkler tank leads to electrical
energy savings of up to 43%. Purchasing electricity on the EPEX SPOT market leads
to additional costs savings of up to 17%. The total energy savings highly depend
on the weather conditions and the prediction horizon.
