© 2022 Author(s).Solar particle receivers promise higher operating temperatures compared to molten salt-based receivers. The Discrete Element Method (DEM) tool LIGGGHTS is used to simulate the particle motion in a centrifugal solar particle receiver. A separate thermal model is developed in MATLAB, which uses the particle positions calculated with the DEM simulation. Heat transfer at the particle scale is accounted for with models of particle-particle conduction, particle-fluid- particle conduction, and a newly developed short-range radiation model. Radiation between large internal surfaces of the receiver are modeled with a view factor based long-range radiation model, and concentrated incident radiation is modeled with the Monte Carlo method. A thermal simulation for a lab-scale receiver is run for a relevant set of operational parameters, with key results being the temperature distribution and thermal efficiency of the receiver.

Energy preserving reduced-order modeling of the rotating thermal shallow water equation Karasözen, Bülent; Ylldlz, S.; Uzunca, M. (2022-05-01) © 2022 Author(s).In this paper, reduced-order models (ROMs) are developed for the rotating thermal shallow water equation (RTSWE) in the non-canonical Hamiltonian form with state-dependent Poisson matrix. The high fidelity full solutions are obtained by discretizing the RTSWE in space with skew-symmetric finite-differences, while preserving the Hamiltonian structure. The resulting skew-gradient system is integrated in time by the energy preserving average vector field (AVF) method. The ROM is constructed by...
Linear and nonlinear optical characteristics of PbMoO4 single crystal for optoelectronic applications Delice, S.; Isik, M.; Hasanlı, Nızamı (2022-10-01) © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.In the present paper, we studied linear and nonlinear optical properties of lead molybdate (PbMoO4) single crystals grown by Czochralski method. Raman measurement was performed in the range of 50–1000 cm−1 and 11 active vibration modes were defined in the spectrum. The nature of the observed modes was discussed in detail. Optical absorption of the material was investigated utilizing room temperatu...
Real-time measurement of laser beam characteristics for a waterjet-guided laser machine Subasi, Levent; Gökler, Mustafa İlhan; Yaman, Ulaş (2022-01-01) © 2022, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.Waterjet-guided laser machining is a novel process used for precision cutting and drilling of various materials and geometries. There are many noise factors in the process affecting the laser beam characteristics, namely the effective cutting length and laser power in the waterjet. Although these variables are mainly set by the laser and waterjet parameters, uncontrollable factors result in variations. Pre...
Predictive Design and Analysis of Drug Transport by MultiScale Computational Models Under Uncertainty Akalın, Ali Aykut; Dedekargınoğlu, Barış; Choi, Sae Rome; Han, Bumsoo; Özçelikkale, Altuğ (2022-01-01) © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Computational modeling of drug delivery is becoming an indispensable tool for advancing drug development pipeline, particularly in nanomedicine where a rational design strategy is ultimately sought. While numerous in silico models have been developed that can accurately describe nanoparticle interactions with the bioenvironment within prescribed length and time scales, predictive design of these d...
Valorization of Apple Pomace Via Single Cell Oil Production Using Oleaginous Yeast Rhodosporidium toruloides Tuhanioglu, Arda; Hamamcı, Haluk; Alpas, Hami; Çekmecelioğlu, Deniz (2022-01-01) © 2022, The Author(s), under exclusive licence to Springer Nature B.V.Apple pomace was used as a sole raw material for single cell oil (SCO) production by the oleaginous yeast Rhodosporidium toruloides DSM 4444. Preliminary studies with glucose medium revealed 100 mL of working volume in 500 mL Erlenmeyer flask as the most efficient in terms of lipid content. Thus, apple pomace hydrolysate was tested in six different conditions using 100 mL medium. The detoxified hydrolysate without chemical supplement (D m...
