It's not exactly possible to increase blood flow to the veins but if you want to increase blood flow to the heart or a certain muscle or the body in general extercise is probably the best option.
Isoxsuprine is a vasodilator that relaxes blood vessels to improve blood flow. When mixed with dextrose in water, it can be used as a solution for intravenous administration to help increase blood flow to certain parts of the body, such as the limbs or uterus.
An increase in heat causes blood vessels to dilate, which increases blood flow in the body.
Yes, heat can increase blood flow in the body by dilating blood vessels and improving circulation.
No, applying ice causes vasoconstriction, which reduces blood flow to the area. Ice helps to decrease inflammation and swelling by restricting blood flow. Heat, on the other hand, can increase blood flow and promote healing in some situations.

Except in cases of massive blood loss, it's not the job of the vessels to increase or decrease blood flow, but of the capillary beds.
The arrangement of blood flow in the limbs of penguins is that of a counter-current exchange system where the cold blood coming from limbs flows parallel but in the opposite direction then the hot core-temperature blood coming from the heart. As the the hot blood flows outward it re-warms the venous blood which in turns cools down the arterial blood.
