Abstract

Three-dimensional computational fluid dynamic simulations were conducted for flow and heat transfer characteristics around flat fin with staggered tube arrangement to fulfill the cooling performance of the tube fin heat exchanger. Fins are generally used to increase the heat transfer area, so the fin material has a high impact on the heat transfer rate. The material wall fin and tube were changed in three steps: aluminum, steel, copper with two different velocities of 8 and 15 m/s flowing between fins. The geometry of the flat fin and tube used staggered tube arrangement using transversal spacing, ST, of 11.8 mm, longitudinal spacing, SL, of 22.2 mm, and flow depth 66.6 mm. GAMBIT 2.6 software was used to meshing the geometry, and FLUENT 18.0 was implemented to simulate flow and heat transfer. The results show that the fin with copper material has a more uniform temperature distribution along the fin than the other materials. This indicates that the copper material has a higher heat transfer rate compared to aluminum and steel. Furthermore, increasing velocity will make the separation point formation farther behind the tube and decrease the recirculation zone. Moreover, 8 m/s has a lower outlet temperature than 15 m/s. As a result, 8 m/s and copper material have the highest effectiveness of 16.47 and efficiency of 88.35 %. The use of copper and aluminum as fin material will also have the relatively same performance in the heat exchanger.

Abstract

Stroke represents a condition that occurs when the blood supply to the brain is interrupted or reduced due to a blockage (ischemic stroke) or rupture of a blood vessel (hemorrhagic stroke). A person who suffers a stroke will have a brain disorder that causes him/her unable to carry out activities like other healthy people. In general, stroke sufferers have paralysis in several parts of the body, like the hands, feet, and even the face. With technological developments in this era, stroke can be healed in various ways that have been developed by health experts. Healing can be referred to the treatment result for blocked or damaged blood vessels. However, the sufferer’s paralysis cannot return to the normal condition immediately, so it requires therapy or exercises to stimulate the muscles in the hands, feet, or face. This study focuses on developing a therapeutic device on the wrist that has a swivel joint. To design the wrist rehabilitation device with servo motor drive, some researches about existing products need to be reviewed. From that, a list of requirements is compiled, which is used for designing the concept of a wrist rehabilitation device. It is expected that an automatic wrist rehabilitation device can help post-stroke patients undergo the rehabilitation process.
