One example of matlab heat exchanger is matlab programming radiator on your car, but there are lots of others. Heat exchangers are utilized in refrigeration, air con, chemical manner plant, and space heating, to name matlab few. Although matlab programming Dittus Boelter correlation is not flawlessly accurate, it is useful for some purposes and is expected to be, on accurate to within 15 percent. Using matlab programming Dittus Boelter correlation matlab programming heat transfer coefficient can be calculated in matlab programming following way using two further dimensionless groups, matlab programming Reynolds number and matlab programming Prandtl number: where kw is matlab programming thermal conductivity of matlab programming liquid, DH is matlab programming Hydraulic diameter, and Nu is matlab programming Nusselt Number that’s decided by matlab programming following equation:For matlab programming Reynolds number, m is the same as matlab programming mass flow rate, and matlab is matlab cross sectional area of flow taken from matlab programming tube. For matlab programming Prandtl number, Cp is equal to heat potential assuming matlab fixed pressure, and in both equations, is matlab programming viscosity of matlab programming fluid in attention. The Reynolds number is matlab measure of matlab programming relative significance of viscous and inertial forces on the way to bring forth turbulence.
