6 FAQs about [Baffle type energy storage device]
What baffle configurations are used in sthe thermo-hydraulic performance?
This study enriches the STHE thermo-hydraulic performance using different baffle configurations (BC) such as single segment, double segment, single helical, single segment—no tubes in window (NTIW), propeller type and spiral baffle.
Can baffle plates improve the performance of solar storage tanks?
Although the use of baffle plates to improve the performance of solar storage tanks during charging by altering the incoming flow from the collector has been explored in the literature, the potential benefit of baffles in reducing heat loss in the absence of the external flow has not been investigated.
Which helical baffle configuration is optimum heat transfer performance?
The overall heat transfer coefficient for single Helical 15° and double segmental Baffle configuration is lower than other baffle configurations analyzed by HTRI and CFD. Based on heat transfer performance, number of transfer units, and effectiveness, a single Helical 15° is optimum heat transfer performance related to all others.
What role does a baffle plate play in a heat exchanger?
The baffle plate not only plays a conductivity role on the fluid but also plays a limited role on the heat exchange tube beam. The heat exchanger is composed of 20 rows (Z direction) and 13 rows (X direction) of 260 heat exchange tubes, the inner diameter of which is 50 mm and the thickness is 1 mm.
What are the characteristics of heat exchange tube bundle and baffle plate?
The hot and cold fluid are, respectively, on both sides of the heat exchange tube bundle and baffle plate, and the coupling boundary is adopted. The heat transfer coefficient of the tube wall is 0.2 W/ (m K), the density is 2,190 kg/m 3, the linear expansion coefficient is 1.2 × 10 −6 /°C, the tensile modulus is 280 MPa, and the strength is 25 MPa.
Do baffled solar storage tanks reduce heat loss?
Heat loss from jacketed baffled solar storage tanks is examined. Baffles can reduce heat transfer coefficients by up to 40%. A long baffle near the wall provides most benefit. Solar water heating systems with thermal storage are one of the simplest ways of reducing energy demand for domestic water heating.
