چکیده
|
Forced convective condensation in vertical channel is investigated numerically. the condensation boundary layers that occur due to temperature difference between the walls and saturation temperature of steam is simulated by the volume of fluid (vof) method. the effect ef variations in the hydraulic diameter, steam velocity, re number and temperature difference between the wall and saturation temperature of inlet steam on heat transfer coefficients are investigated. simulation results showed that the condensation length and heat transfer coefficient increase by the increase in the amount of inlet velocity and reynolds number of inlet steam. also, it was seen a reduction in temperature difference between the wall and saturated steam.
