Patent number: 11867457Abstract: A hybrid shellfish cooling system employs DC and AC cooling units using both solar power and AC electrical supply as energy sources. As temperature control and uniform temperature distribution in the cooling system are critical factors in reducing vibrio growth on raw oysters and reducing energy consumption, the system is equipped with a divider that optimizes airflow through the cooling system interior cabinet to achieve uniform temperature distribution in six individual internal compartments. Tests indicated that an average of 130 min. cooling was required to reach the suggested oyster temperatures of 7.2° C. and meet the cooling time requirement (i.e., 10 h or less). Airflow is further optimized via fan location and airflow direction, whereby configuration of a circulation fan on a lower part of the 12-volt DC section with an air supply from the 12-volt DC section to the 110-volt AC section achieves relatively uniform temperature distribution.Type: GrantFiled: June 13, 2022Date of Patent: January 9, 2024Assignee: Morgan State UniversityInventors: Seong W.

As temperature control and uniform temperature distribution in the cooling system are critical factors in reducing vibrio growth on raw oysters and reducing energy consumption, the hybrid shellfish cooling system is equipped with a specially configured divider that optimizes airflow through the cooling system interior cabinet to achieve uniform temperature distribution in six individual internal compartments inside of the cooling system. Test results indicated that an average of 130 min. cooling was required to reach the suggested oyster temperatures of 7.2° C. and meet the cooling time requirement (i.e., 10 h or less).Type: ApplicationFiled: June 13, 2022Publication date: December 22, 2022Inventors: Seong W.

Publication number: 20210190311Abstract: Disclosed is a system and method for the combustion of biomass material employing a swirling fluidized bed combustion (SFBC) chamber, and preferably a second stage combustion carried out in a cyclone separator. In the combustion chamber, primary air is introduced from a bottom air box that fluidizes the bed material and fuel, and staged secondary air is introduced in the tangential direction and at varied vertical positions in the combustion chamber so as to cause the materials in the combustion chamber (i.e., the mixture of air and particles) to swirl. The secondary air injection can have a significant effect on the air-fuel particle flow in the combustion chamber, and more particularly strengthens the swirling flow, promotes axial recirculation, increases particle mass fluxes in the combustion chamber, and retains more fuel particles in the combustion chamber. This process increases the residence time of the particle flow.Type: ApplicationFiled: March 9, 2021Publication date: June 24, 2021Inventors: Seong W.

Publication number: 20200075182Abstract: Provided are a nuclear fuel rod for fast reactors that includes a metallic fuel slug coated with a protective coating layer and a fabrication method thereof. The nuclear fuel rod for fast reactors that includes a surface treated metallic fuel slug and a cladding tube according to the present invention has an excellent effect of stabilizing components of the metallic fuel slug and fission products or impurities, because the interdiffusion between the metallic fuel slug and the cladding tube does not occur. Also, since the uniform coating on the surface of the metallic fuel slug may be facilitated and fabrication costs may be significantly reduced in comparison to a typical technique of using a functional material for preventing the interdiffusion at an inner surface of the cladding tube, it may be suitable for fabricating the nuclear fuel rod for fast reactors.Type: ApplicationFiled: April 25, 2019Publication date: March 5, 2020Inventors: Chan Bock Lee, Jun Hwan Kim, Jong-Hyuk Baek, Jin-Sik Cheon, Byoungoon Lee, Ki H.
