The porous sphere set up consists of a liquid fuel feed system, wind tunnel and a porous alundum sphere. The porous sphere is prepared from white aluminium oxide and powdered fire clay. A stainless steel hypodermic needle of diameter 1.2 mm has been used to support the alundum sphere. Uniform distribution of fuel inside the porous sphere is ensured by drilling radial holes of 0.4 mm diameter at the end of the hypodermic needle. The other end of the needle is fixed to a glass syringe. An infusion pump is used to supply the fuel. The sphere is supported in front of an air flow system, which consists of a low turbulence wind tunnel of 200 mm diameter. Mass burning rate is measured by noting down the fuel flow rate (ml/h) from the syringe.
