WebMar 16, 2012 · Capillary channels are formed from silicon substrates with 100 µm widths. Varying depths are studied that range from 57 to 170 µm. Operation of the boiler shows increasing flow-rates with increasing capillary channel depths. Maximum fluid mass transfer rates are 12.26 mg/s from 170 µm channels, an increase of 28% over 57 µm channel … WebThe energy input, Qin, to a combustion chamber is the product of fuel mass flow rate and higher heating value, HHV (about 23,900 Btu/lbm for natural gas). Qin = mf HHV (3) The combustion gas mass flow rate, mg, is the sum of the fuel mass flow rate and combustion air mass flow rate. mg = mf + ma (4) The combustion temperature, Tc, can be ...
