Abstract

A mathematical model for the channel analysis of MHD generators based on nonlinear fluid dynamics and Maxwell´s equations has been presented. The fluid properties of the seeded combustion products of coal burnt with oxygen enriched/preheated air, needed for the present analysis, have been obtained by using a computer program based on the principle of minimization of Gibb´s free energy (NASA-SP-273). This has been used to study the variation of different flow parameters inside the MHD channel, Thus, the power generated by the Indian MHD retrofit channel (having segmented geometry) has been estimated under different operating conditions. The limitation imposed due to electrical stress on the insulating walls and due to slagging have also been considered for limitation of power output from the channel
