## NUMERICAL STUDY OF THE EFFECT OF TRIANGULAR SURFACE WAVES OF VARYING HEIGHT ON NATURAL CONVECTIVE HEAT TRANSFER FROM AN UPWARD FACING HEATED ISOTHERMAL HORIZONTAL SURFACE
## 要約A numerical investigation of natural convective heat transfer from a horizontal upward facing isothermal
heated surface having a series of equally spaced triangular shaped waves and imbedded in a flat adiabatic surface was undertaken. Most previous studies of this situation dealt with the case of waves of constant height. The possibility of increasing the heat transfer rate enhancement of surface waves by using waves of varying height was numerically investigated. Waves decreasing linearly in height from the center of the surface to the edge of the surface and waves increasing linearly in height from its center to the edge of the surface were considered. Two-dimensional steady flow was assumed. The Boussinesq assumption was adopted in dealing with the buoyancy forces. The solution was obtained using the commercial CFD solver ANSYS FLUENT |
