How To Design The Optimal Heat Exchanger From The Quran?

And Allah (God) sends down from the Qur‘an that which is healing and mercy to those who believe, and it increases the wrong-doers nothing but loss. The Qur’an(17(: 82

Designing The Optimal Heat Exchanger from The Quran

Where to start?

In The Name of Allah (God) The Most Compassionate The Most Merciful

And in your own selves, will you not then see? The Noble Qur’an (51: 21)

The Skin

‫جلد النسان‬ COLDER REGION INTERFACE HOT REGION

Studying The Design of Human Skin 1. The Morphology of The Outer Surface of The Skin

Skin’s outer surface has the shape of water waves

We learn that we need to design the outer surface of the heat exchanger to have the shape of water waves in order to have maximum surface area and thus rapid heat transfer

Studying The Design of Human Skin 2. Objects Found on The Outer Surface of The Skin (i.e. Hair)

In The Name of Allah (God) The Most Compassionate The Most Merciful

And it is Allah (God) Who sends the winds, so that they cause turbulence in the clouds, and Allah (God) drives them to a dead land, and revives therewith the earth after its death. As such the Resurrection The Qur’an (35:

Human Skin

exagonal Arrangement of Hairs in Human Ski

Hexagonal Arrangement of Hairs in Human Skin

A Single Hair The Pattern of Wind Flow on Human Skin

Slow transfer of heat from the body in addition to large friction due to flowing fluid

A body which does not contain projections on its surface

Large transfer of heat from the body due to turbulence of the flowing fluid caused by projections found on the surface, in addition to lower friction

A body containing projections on its surface

Studying The Design of Human Skin 3. The Thickness of Skin

Small thickness for the skin which reduces the resistance to heat transfer which yields fast heat exchange

Studying The Design of Human Skin 4. The Shape of The Skin

The skin has a smooth shape which ensures no formation of hot spots (i.e. heat concentration regions) and thus no pain and smooth flow of heat which yields fast heat

Explanatory Example

The design of a heat exchanger having a surface shaped like water waves

Calculating the heat flux from a heat exchanger having a surface shaped like water waves

Maximum value for heat flux = 47 Watts per meter square

A comparison between two designs for a heat exchanger, one having outer wavy surface and another having flat outer surface

Calculating the heat flux for a heat exchanger having a flat outer surface The maximum value for heat flux ((Exchanger with flat outer surface Watts per meter square 37 =

A comparison between heat flux values for the two designs 

A heat exchanger having a flat outer surface 



37 Watts per meter square

A heat exchanger having a wavy outer surface 

47 Watts per meter square

This example shows how by applying the design concepts found in the design of Allah (God) for human skin, the efficiency of heat exchange can be significantly increased
