DescriptionThe study of global warming and its effects is becoming increasingly popular due to steady increase in the environmental pollution. Local warming of a particular place which in turn contributes to the global warming can be studied through temperature variations of the local water bodies due to changes in the environment. In the present work, using the weather data obtained for New Brunswick, a general trend for variation in ambient temperature during the year is determined by fitting suitable curves using curve-fitting technique. Using this, the transient temperature distribution in the lake is determined numerically. The effect of many driving parameters such as ambient temperature, relative humidity, wind speed, solar flux, equilibrium temperature, diffusivity and surface heat loss on the temperatures of the lake are studied in detail using a one-dimensional transient model. The governing equations are solved numerically using finite differences method. The results of this work show the transient temperature distribution in the lake over the year and the variation in temperatures due to external changes in the environment.
