Mathematical Model: Thermal Effects of Two Wheeler Rider’s Speed in His/Her Eye

Abstract

High speed airflow into the cornea accelerates evaporation and heat transfer. Eyelid blinking increases with increased airflow speed into the eye. Increased blinking increases corneal temperature when drops below normal level. In cold climatic condition high speed airflow causes rapid temperature drop. Most often, eye injuries caused by cold exposure occur in individuals who try to force their eyes open in high speed wind and cold weather such as two wheeler rider. The purpose of this study is to investigate the temperature changes in two wheeler rider’s cornea, considering eyelid blinking, in his/her different speed. Thus, in this paper, bio-heat transfer process is simulated using finite element method at rider’s different speed in transient state cases. In still air, blinking increases corneal temperature by $2.74^oC$ at normal ambient temperature $22.5^oC$ than in open eye. At ambient temperature $0^oC$ and rider’s speed $60km=hr$, corneal temperature drops to $5.45^oC $ in open eye, while blinking increases this temperature by 6:28oC. Similarly at ambient temperature $40^oC$, blinking reduces corneal temperature by $0.51^oC$. Corneal temperature approaches steady state quickly at higher rider’s speed.
