Thermohydraulic Performance of a Packed Bed Solar Energy Storage System

2021
In the present scenario, solar energy is one of the sustainable solutions to limit the greenhouse gases emitted by conventional energy systems. But solar energy is intermittent. So in order to use solar energy when it is not available, energy storage is required.

Optimising the thermohydraulic performance of rough surfaces

International Journal of Heat and Mass Transfer, 1975
Abstract The parameters which control the momentum- and heat-transfer performance of a rough surface in a uniform channel flow are presented in a novel way. A new efficiency parameter is denned for optimising this performance. Using a recently developed analysis a wide range of rough surfaces are investigated and design charts presented.

Thermohydraulic Performance of Packed Bed Solar Air Heater

2020
An experimental investigation is carried out as per ASHRAE standards on a high porosity packed bed solar air heater. Packed bed is generally used to enhance the heat transfer area and also for storage of thermal energy. The work covers a particular range of design and operating parameters. Design parameters include the colour of packing material (black

A review of thermohydraulic performance of artificially roughened solar air heaters

Renewable and Sustainable Energy Reviews, 2014
Abstract Solar air heaters form the major component of solar energy utilization system which absorbs the incoming solar radiation, converting it into thermal energy at the absorbing surface, and transferring the energy to a fluid flowing through the collector.

Effect of Air Gap on thermohydraulic performance of finned tube bundles

Thermal Science and Engineering Progress, 2020
Abstract The air gap between the consecutive tube bundle row fins is one of the most important parameters that have not been evaluated in terms of their impact on the performance of air-cooled condensers. In this paper, the effect of this air gap on the thermo-hydraulic performance of the tube bundle air-side flow is investigated.

Effect of Flow Arrangements on Thermohydraulic Performance of a Microchannel Heat Sink

ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 3, 2009
The advancements in fabricating and utilizing microchannel heat sinks (MCHS) for cooling of electronic devices during the last decade has not been matched by corresponding advances in our fundamental understanding of the unconventional micro fluidics. Many theoretical and experimental studies have been reported for the heat transfer analysis along the ...

Effect of Plenum Shape on Thermohydraulic Performance of Microchannel Heat Sink

Journal of The Institution of Engineers (India): Series C, 2019
Heat sinks, cooled by flowing fluid in the microchannels fabricated upon them, successfully proved effective cooling solution in electronic components. The entire thermal output of such a heat sink depends upon the characteristics of fluid flowing in the channels and the plenums placed subsequently at inlet and outlet positions.

Thermohydraulic performance of some ribbed surfaces and their choice for GCFR

Annals of Nuclear Energy, 1976
Abstract In this report the thermohydraulic performances of several types of artifically roughened surfaces provided for use in GCFR have been investigated experimentally and compared. The tests were performed with air in an annular test rig. The favourable dimensionless rib parameters as suggested by other authors are confirmed. Besides an important

Optimal thermohydraulic performance of artificially roughened solar air heaters

Solar Energy, 1991
Abstract The heat transfer coefficient of solar air heaters can be increased by provinding artificial roughness on the bottom of the absorber plate, leading to higher collection efficiency. Inclusion of artificial roughness, however, results in a higher friction factor and consequently a higher pumping power is required.
