... mass diffusion skin friction Many engineering problems are susceptible to MHD analysis. Geophysicists encounter MHD phenomena in interactions of conducting fluids and magnetic fields. Engineers apply MHD principles in designing of heat exchangers, pumps and flow meters, and power generating...

... conductivity conduction mass diffusion approximate solutions Analytical solutions for one-dimensional, constant property, transient conduction (or species diffusion) within objects having simple geometries (plane wall, infinite cylinder, and sphere) have been known for decades and are presented...
