3. 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?
4. 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:
5. 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.

In the special cases of wave propagation of heat in
an isotropic and homogeneous medium in a 3-
dimensional space, this equation is’

13. Future trades
heat equation the future trades are 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.
14. 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.
15. 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.
16. 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.
