heat equation [′hēt i‚kwā·zhən] (thermodynamics) A parabolic second-order differential equation for the temperature of a substance in a region where no heat source exists: ∂t/∂τ = (k/ρc)(∂2t/∂x2+ ∂2t/∂y2+ ∂t2/∂z2), wherex, y,andzare space coordinates, τ is the time,t(x,y,z,τ) is the temperature,kis the thermal conductivity of the body, ρ is its density, andcis its specific heat; this equation is fundamental to the study of heat flow in bodies. Also known as Fourier heat equation; heat flow equation. How to thank TFD for its existence?

| 1) Creation of a cross-linked structure of carbon fiber through use of a unique binder in the polylactic acid (PLA)*1 resin achieves high heat diffusion (with carbon fiber of 10% and 30% the heat diffusion ability of the new bioplastic composite is comparable to and double that of stainless steel respectively). Noble Biomaterials is best known for X-STATIC - The Silver Fiber([R]) that has harnessed the anti-odor, anti-microbial, anti-static and heat diffusion properties of silver by permanently bonding a layer of pure silver to fiber. This interfacial layer made of Ta2O5 prevents heat diffusion from the phase-change film via the plug. |
