WebJan 22, 2015 · The lumped capacitance method is used since the introduction of corrected heat transfer coefficients between solid and fluid extends the validity of this method to large Biot numbers. The discharging performance of four typical concrete structures including the channel-embedded structure, the parallel-plate structure, the rod-buddle structure ... WebIf your object is a cylinder placed horizontally the characteristic length is determined by the diameter D of the cylinder. The characteristic length is commonly defined as the volume of the body divided by the surface area of the body, i.e. The surface area should include the top and bottom of the cylinder.
