Study of the required thermal insulation (IREQ) of clothing using infrared imaging
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
The sense of cold develops due to the increase in heat loss from a human body. Excessive cold can be a health hazard, since excessive heat loss from the body may result in hypothermia/frostbite. Decreased body temperature due to heat loss also affects the physical, manual and perceptive performance of individuals. Therefore, protective measures are taken through clothing that controls and regulates ...
Detection of Red Dye in Diesel Oil
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
Developing a sensitive and effective instrument for detecting the presence of red dye in diesel fuel is very advantageous for governments in preventing tax loss by controlling illegal use of the diesel fuel.
The objective of this work has been to investigate and develop an instrument to detect red dye in diesel, based on the principle of absorption. The peaks of absorption in red and pure diesel ...
Sound waves in fluidized bed using CFD–DEM simulations
(Journal article; Peer reviewed; Tidsskriftartikkel, 2017-10-16)
The speed of sound waves is investigated using CFD-DEM numerical simulations. Appropriate initial and boundary conditions are applied to capture the phenomenon. The effect of varying the height of the bed is also studied. The results of the simulations matched those from literature. The pressure and particle velocity profiles from the simulation showed the oscillatory behavior. Functions (based on ...
Fluid solid interaction simulation of CFRP shell structure
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
This work attempts to model the dynamic behavior of Carbon Fiber Reinforced Polymer (CFRP) shell structure subjected to water shock wave to improve the results presented in the study by Khawaja et al., 2014. In the previous study, the real physical problem was simplified by decoupling the fluid and the structural phenomena, applying the recorded experimental fluid pressure load to the CFRP shell ...
