Certain Heat Conduction Problems In a Perforated Circular Cyliner
Employing a new class of basis functions, certain steady-state two-dimensional heat conduction problems for a multihole circular cylinder are solved. It is assumed that the outer boundary of the cylinder is subject to convection, while the cases of the following inner boundary conditions are investigated. (1) The inner boundaries are subject to a constant temperature. (2) The inner boundaries are subject to convection. (3) The inner circular cylinders consist of a different material containing uniform heat sources. It is also assumed that the properties of the materials involved, and the factors such as the convection heat transfer coefficients are temperature independent. Numerical results for all of the three aforementioned cases are presented, and for a particular case, the result is compared with that of a previous investigator.
