Introduction The purpose of our
presentation is to what is the heat equation
that we are able to model the flow of heat through an object.
But before we begin our discussion of the mathematics of the heat
equation, we must first determine what is meant by the termheat?
heat equation The heat equation arises in
the modeling of a number of phenomena and is often used in financial mathematics in the modeling of options. The famous Black-Scholes option pricing model's differential equation can be transformed into the heat equation allowing relatively easy solutions.
More generally in any coordinate system:
One dimensional equation The heat equation is derived from Fourier's
law and conservation of energy (Cannon 1984). By Fourier's law. A uniform homogenous rod is made of infinite number of molecules. They are interconnected by cohesive force.

famous Black–S uchholes option pricing model's differential equation can be transformed into the heat equation allowing relatively easy solutions from a familiar body of mathematics.
Many of the extensions to the simple option models do not have closed form solutions and thus must be solved numerically to obtain a modeled option price. The equation describing pressure diffusion in a porous medium is identical in form with the heat equation.
Heat transform The increased circuit density on today’s computer
chips is reaching the heat dissipation limit of air cooling technology. The direct liquid cooling of chips is being considered as a viable alternative. A broad range of industries is driving the development of compact, advanced cooling technology. One of the most important of these applications is the removal of high heat fluxes in microelectronic circuitry.
working of heat transform Fluid enters the loop from a reservoir
through a filter and is continuously circulated by a peristaltic pump. Constant temperature bath is at upstream of the setup.
which controls the inlet flow temperature and maintained constant temperature of fluid and it goes to mini channel
Aluminum is selected as substrate because of relatively high thermal conductivity (204.2w/mk) and low mass density with high strength.
conclusion The heat equation equation also has immense
amounts of use in Biology where it is know as the if-fusion equation and models the diffusion of a substance through a system. We have only examined the case where heat flows in one direction through a thin rod.
